The Ultimate Guide To China Quantum Computing Companies In 2026 - Quantum Zeitgeist

Expand All Not Your Typical Startup Ecosystem Forget the Silicon Valley playbook. China’s quantum companies are mostly spinouts from CAS labs and elite universities, brought to market on state-guided capital, provincial procurement contracts, and SOE backing. A few private VCs are now showing up, but the engine is industrial policy, not Sand Hill Road. What Actually Exists The world’s largest quantum communication network: 12,000 km, 145 nodes, 17 provinces, two satellites in orbit. The Jiuzhang photonic series has demonstrated quantum advantage over classical supercomputers. Zuchongzhi superconducting processors benchmark directly against Google. And behind all of it, a government procurement machine large enough to keep companies solvent for years before commercial markets arrive. The National Team  ·  量子国家队 Three companies define the core. QuantumCTek holds the only pure-quantum listing on a Chinese exchange, now under China Telecom’s control, and supplies the hardware running the national QKD backbone. Origin Quantum is the computing name everyone knows — 72-qubit Wukong, IPO in process at around ¥6.9 billion. CIQTEK, the quantum instruments and sensing specialist, got its STAR Market IPO approved in December 2025 at roughly ¥11.7 billion implied valuation. The Rest of the Field Trapped ions: Hyqubit, Huayi Quantum, QuDoor, Unitary Quantum. Neutral atoms: CAS Cold Atom, MatriQ, Buchou Quantum, Liangyi Wanxiang. Photonics: QBoson, TuringQ, Guizhen. Superconducting: LogicBit, Coherent Technology. QKD hardware: QuantumCTek, Qasky, LuxQuanta. QKD networks: Guoke Quantum. Sensing: Kewei, Guosheng, CIQTEK. Software and quantum-inspired: ArcLight, e-Spin. Most are on Quantum Avenue in Hefei or in Zhongguancun, Beijing — the concentration is deliberate, proximity to USTC and CAS research groups is the whole point. What the Entity List Actually Did US export controls on QuantumCTek, several CAS institutes, and a string of supply-chain firms were meant to slow China down. The effect has been the opposite: a crash programme in domestic dilution refrigerators, low-temperature electronics, and photonic components, with Q4 2025 producing funding rounds across every major qubit modality at once. The restrictions handed Chinese quantum manufacturers a political mandate and a captive market. Superconducting Hardware Superconducting qubits are China’s primary focus for gate-model quantum computing, anchored by USTC’s Zuchongzhi research programme and Origin Quantum’s commercialisation of that work. China Telecom’s Tianyan platform provides cloud access to superconducting systems totalling 880 qubits across four machines. A third strand is now emerging: LogicBit, a Zhejiang University spinout, is pursuing the quantum error correction and logical qubit layer that will determine long-term fault tolerance, explicitly benchmarking against Google’s architecture. Origin Quantum  本源量子 Superconducting Full-Stack · Hefei, Anhui · $294M raised · 72-qubit Wukong · IPO pending Superconducting Pre-IPO Origin Quantum is China’s most vertically integrated quantum computing company, the only commercial entity to have built a complete domestic manufacturing chain for superconducting quantum computers from chip fabrication through operating system to cloud platform a deliberate architecture designed to operate entirely without Western components. Founded in 2017 by Guo Guoping and Kong Weicheng as a spinout from the University of Science and Technology of China in Hefei, Origin Quantum operates alongside the Anhui Quantum Computing Engineering Research Center the same research infrastructure behind the academic Zuchongzhi series of processors. Its commercial flagship is Origin Wukong, a 72-qubit superconducting processor named after the Monkey King of Chinese legend, launched January 2024 as the most advanced commercially deliverable quantum computer produced in China. In the first year, Wukong attracted over 20 million cloud visits from users in 145 countries and completed more than 530,000 quantum computing jobs. Its fourth-generation control system, Benyuan Tianji 4.0, released in 2025, supports over 500 qubits and represents the first Chinese measurement and control system with fully replicable, scalable engineering capability for mass production. In February 2026, Origin Quantum open-sourced its Origin Pilot operating system the “soft heart” of the quantum computing stack positioning itself as both hardware and software infrastructure for China’s quantum ecosystem. Origin Quantum has raised $294 million, including a $148 million Series B round from the Anhui provincial government and the Chinese Academy of Sciences a funding structure that gives the company extraordinary runway but also anchors its incentives firmly to domestic government priorities. It holds more quantum computing patents than any other Chinese company and ranks sixth globally by patent portfolio. The company has deployed Origin Wukong to real-world applications including breast cancer screening analysis and quantum computational fluid dynamics. An IPO on the STAR Market is anticipated, with a recent valuation of approximately 6.9 billion RMB (roughly $950 million). Supply-chain self-sufficiency: Origin Quantum established China’s first dedicated quantum chip production line, developed the country’s first quantum operating system, and in 2024 began factory production of dilution refrigerators the cryogenic cooling systems that had previously been sourced entirely from European suppliers. Each component closed represents a reduction in the export-control exposure that the US entity list created for USTC-linked institutions. The company imports lithographic machines from Germany’s SÜSS MicroTec for chip fabrication, one visible remaining dependency. China Telecom Quantum Group  天衍量子 State Quantum Cloud · Hefei, Anhui · Tianyan-504 · Controlling shareholder of QuantumCTek · SOE Cloud Platform SOE China Telecom Quantum Group is the state-owned enterprise that has positioned itself as the national infrastructure layer for quantum computing and quantum-secure communications the organisation most likely to determine how China’s quantum technology reaches enterprises, government, and eventually consumers at scale. Established as a wholly-owned subsidiary of China Telecom and headquartered in Hefei, China Telecom Quantum Group became the controlling shareholder of QuantumCTek in January 2025, consolidating quantum computing and quantum communications into a single SOE-anchored entity with more than CNY 10 billion of planned investment across its quantum programmes. Its flagship initiative is the Tianyan quantum computing cloud platform, which combines the Tianyan-504 a 504-qubit superconducting quantum computer co-developed with CAS and QuantumCTek, announced December 2024 with the commercially deployed Zuchongzhi-3 (105-qubit system accessible via the platform from October 2025). By mid-2025, the Tianyan platform had received more than 12 million user visits from over 50 countries. The Tianyan-504’s qubit count is among the largest of any system outside IBM and is reported to solve certain problems 450 million times faster than leading classical supercomputers a claim that, like most quantum advantage demonstrations, applies to specific narrow problem types. China Telecom’s QKD business distributes quantum encryption keys to over 5 million users through SIM cards, and operates a QKD-secured cloud service targeting government and financial sector clients. China Mobile runs a parallel platform, Wuyue, that is hardware-agnostic and hosts photonic (QBoson) and trapped-ion systems alongside superconducting hardware the two carrier-operated platforms represent China’s most direct counterpart to IBM Quantum and AWS Braket. Why the SOE model matters here: The Western quantum cloud race is driven by enterprise SaaS economics. China’s carrier-operated quantum cloud is driven by infrastructure policy: the same state logic that built the national QKD backbone network is now being applied to quantum computing access. Government agencies, state-owned banks, and utilities are the first commercial customers, ensuring revenue without needing to win enterprise sales cycles. The risk is that the model optimises for domestic government procurement rather than global technical competitiveness. LogicBit  逻辑比特 Superconducting QEC · Hangzhou · Zhejiang University spinout · Pre-A 2025 · Nature paper 100-qubit chip Superconducting Pre-A LogicBit is one of the most technically credible new entrants in Chinese superconducting quantum computing. The Hangzhou company emerged from one of China’s strongest university-based superconducting qubit research teams, and its founders contributed to a 100-qubit superconducting quantum chip published in Nature in August 2025 work that is explicitly benchmarked against Google’s architecture and approach to quantum error correction. Founded as a spinout from Zhejiang University, LogicBit’s earlier chips include Mogan-1 (a fully-connected special-purpose chip for quantum simulation) and Tianmu-1 (a 36-qubit scalable general-purpose processor with nearest-neighbour connectivity). The Tianmu-1 was made available via JanusQ Cloud, Zhejiang’s first user-facing superconducting quantum cloud platform. LogicBit’s commercial focus is now firmly on error-correctable quantum chips and logical qubit development the layer of hardware that sits between physical qubits and fault-tolerant computation. The company closed a Pre-A round in October 2025, with tens of millions of RMB from a consortium including Zheda United Innovation (ZJU-affiliated), Westlake Science and Technology Innovation Investment, and several state-linked funds. The explicit comparison to Google’s roadmap in investor communications is notable: LogicBit is positioning itself as China’s most technically rigorous answer to the global logical-qubit race. QEC focus: While Origin Quantum and China Telecom focus on qubit scale and cloud deployment, LogicBit is concentrating on error correction and logical qubits. This is a less commercially mature but more technically important objective. If the logical qubit era arrives on the timelines Google and IBM project, companies like LogicBit will prove more consequential than those with larger qubit counts but less rigorous error performance. Coherent Technology  相干科技 Superconducting QC · Beijing · Early Stage Superconducting Early Stage Coherent Technology (相干科技) is a Beijing-based superconducting quantum computing startup that appeared as a representative enterprise at the Beijing Quantum Industry Ecological Innovation Conference in August 2025 alongside Hyqubit, ArcLight Quantum, QBoson, and the neutral-atom company Liangyi Wanxiang. Its presence at the city’s flagship quantum industry event confirms it as an active participant in Beijing’s emerging superconducting cluster, which sits alongside the more established Hefei superconducting ecosystem anchored by Origin Quantum and USTC. Limited public information is available about Coherent Technology’s team, technical approach, or funding. Beijing has historically pursued a “superconducting and photonic dual-track” strategy contrasting with Hefei’s superconducting monoculture and Coherent Technology appears to represent the superconducting element of that city-level hedge. Additional information is expected to emerge as the company completes early funding rounds and moves toward public product announcements. Trapped Ion Hardware Trapped-ion quantum computing is China’s second active hardware frontier. Hyqubit commercialises Prof. Duan Luming’s Tsinghua group and has cloud systems at over 100 qubits with a 300–600 qubit roadmap. Huayi Quantum is a separate Tsinghua Centre for Quantum Information spinout targeting modular ion trap architecture with strong private VC backing. Unitary Quantum in Hefei is pursuing the QCCD modular approach comparable to Quantinuum. QuDoor (Guokaike Quantum) brings the oldest institutional depth in the sector, having built China’s first ion trap on a chip in 2012 and its first quantum measurement and control system in 2015. Four serious players in one modality reflects how quickly the Chinese trapped-ion ecosystem has expanded since 2021. Hyqubit  华翊量子 Trapped Ion · Beijing · Tsinghua/Duan Luming spinout · 2022 · HYQ-B100 (100+ qubits) · Series A hundreds of millions RMB (Jul 2025) Trapped Ion Series A Hyqubit (official English brand; Chinese: 华翊量子, full name 华翊博奥北京量子科技有限公司) is China’s most advanced commercial trapped-ion quantum computing company, founded in January 2022 in Beijing’s Yizhuang Economic and Technology Development Zone as a spinout from Tsinghua University’s Quantum Information Center. Its founder and scientific anchor is Professor Duan Luming, CAS Academician and director of Tsinghua’s quantum information centre whose group holds the world record for the largest site-resolved 2D ion trap quantum simulation (300 qubits in a single trap with individual qubit readout). Hyqubit’s core technical innovation is a proprietary high-dimensional ion qubit array architecture that the company claims was first proposed globally. The first-generation commercial machine HYQ-A37 (37 qubits) launched in April 2023 as China’s first commercial ion trap prototype; the second-generation HYQ-B100 surpassed 100 qubits and is commercially available on HYQ Cloud. CEO Yao Lin confirmed in July 2025 that revenue was on track to grow several times year-on-year, with over 80% from scientific research computing primarily large SOE research institutes including China Mobile Research Institute. The near-term roadmap targets a third-generation system at 300–600 qubits. Hyqubit has built a fully domestic supply chain for its ion trap hardware, a strategic priority given US export restrictions on cryogenic and precision instrument components. Funding history: Pre-A (May 2024, 100M+ RMB, led by CCTV Convergence Media Fund, co-invested by Baidu Ventures and Lenovo Ventures); Series A (July 15, 2025, hundreds of millions RMB, co-led by the Social Security Fund Zhongguancun Independent Innovation Special Fund managed by Legend Capital, the Beijing Information Industry Development Investment Fund, and Legend Capital directly), with capital earmarked for tech iteration, Gen 2/3 hardware development, and application expansion in 6G communications, operations research, catalytic chemistry, and reservoir simulation. Scientific pedigree: Duan Luming’s Tsinghua group is one of a handful of ion trap teams globally capable of operating at this scale. The 2024 Nature paper demonstrating 300-qubit 2D site-resolved simulation directly validates the HYQ-B100 commercial roadmap. That combination of record-breaking academic results and commercial hardware execution makes Hyqubit’s trajectory significantly more credible than most early-stage quantum hardware startups globally. Unitary Quantum  幺正量子 Trapped Ion QCCD · Hefei · China’s first 4K QCCD chip-type ion trap · Early stage Trapped Ion Early Stage Unitary Quantum is a Hefei-based trapped-ion company pursuing the quantum charge-coupled device (QCCD) architecture the same modular, ion-shuttling approach used by Quantinuum in its H-series systems. In August 2025, the company completed assembly and commissioning of China’s first 4K low-temperature QCCD chip-type ion trap quantum computing system, a technically significant milestone in China’s domestic trapped-ion hardware development. QCCD architectures operate by physically shuttling ions between different trap zones on a microfabricated chip, enabling modular scaling while maintaining the all-to-all connectivity and high gate fidelity that make trapped-ion systems competitive with superconducting processors. Operating at 4K (liquid helium temperature) rather than the millikelvin temperatures required for superconducting qubits is an engineering advantage in system integration. Unitary Quantum received 30 million RMB in funding from Hefei local state-backed investment institutions after needing the capital to deliver its first prototype an example of the municipal government’s direct early-stage support for quantum hardware companies on Quantum Avenue. The company is early-stage, but the 4K QCCD milestone in 2025 marks it as China’s closest domestic analogue to Quantinuum’s hardware approach. QuDoor  国开启量子 Trapped Ion · M&C Systems · Beijing · Founded 2016 · 50M RMB Angel 2021 · Defence, Gov, Finance, Telecoms Trapped Ion Angel QuDoor (full name Guokaike Quantum Technology 国开启量子技术) is one of China’s oldest and most technically credentialled quantum companies, founded in Beijing in 2016. Its R&D team has an exceptional pedigree: the founders were involved in building China’s first commercial QKD system (2003), the first dedicated waveform generator for quantum computing (2007), the first ion trap on a chip (2012), the first quantum measurement and control system (2015), and China’s first ion-phonon-photon compound entanglement system (2018). With 32 quantum information patents, QuDoor has been building the foundational instrumentation of China’s quantum computing supply chain for longer than most of its better-known competitors have existed. In 2021, the company raised 50 million RMB in Angel financing from the Zhongguancun Development Frontier Fund, Zhongguancun Gold Seed Fund, and other investors. QuDoor sits at an unusual intersection: it develops both trapped-ion quantum computer hardware and quantum measurement and control (M&C) systems the classical electronics that interface with quantum processors to read out states and apply gate operations. In the context of China’s domestic substitution push post-US entity list, M&C systems are a strategically critical product category. Foreign-made M&C hardware from companies like Zurich Instruments and Quantum Machines dominated Chinese quantum labs, but US export controls are forcing Chinese hardware companies to find domestic alternatives. QuDoor’s institutional depth in this area having built China’s first such system in 2015 makes it a natural beneficiary of the drive for indigenous control electronics. Its primary markets are defence, government, finance, and telecommunications, giving it a profile more focused on sovereign security applications than on commercial cloud quantum access, distinguishing it from Origin Quantum’s more outward-facing commercial strategy. Huayi Quantum  华翊量子 Trapped Ion · Beijing · CNY 100M+ raised · Tsinghua spinout · Modular architecture Trapped Ion Private Huayi Quantum is a Beijing-based trapped-ion quantum computing company founded in January 2022 by Dr. Lin Yao and a team of PhDs and postdocs from Tsinghua University’s Centre for Quantum Information. Where Hyqubit draws its lineage from USTC and CAS in Hefei, Huayi is the Tsinghua research group’s commercial vehicle, targeting modular and standardised large-scale quantum computers alongside accessible quantum cloud platforms. The company raised over CNY 100 million in its Angel round, led by Gaorong Capital with participation from Sequoia Capital China, Turing Ventures, Aurisco (605116), and MiraclePlus — a notably strong private VC lineup by the standards of Chinese quantum hardware startups, most of which rely on government-guided funds. A further strategic round of approximately ¥100 million followed in January 2024. Huayi’s core technical thesis is modularisation: building standardised, interoperable ion trap units that can be networked rather than scaling monolithic single-trap systems. The company remained active through 2025, attending the Beijing Quantum Industry Ecological Innovation Conference in August 2025 as one of the capital’s representative quantum enterprises. Tsinghua vs USTC — Huayi and Hyqubit are often conflated because both do trapped ions. The distinction matters: Hyqubit commercialises Prof. Duan Luming’s group at Tsinghua (now largely at Michigan), while Huayi is a separate founding team also rooted in Tsinghua quantum information research. Beijing versus Hefei. Different IP, different investors, different architecture bets. Founded January 2022 Location Beijing Modality Trapped Ion Lineage Tsinghua University Centre for Quantum Information Angel Round CNY 100M+ — Gaorong Capital, Sequoia China, Turing Ventures, Aurisco, MiraclePlus Strategic Round ~¥100M — January 2024 Architecture Modular, standardised ion trap units; quantum cloud platform Neutral Atom Computing Neutral atom quantum computing emerged as China’s fastest-growing new hardware modality in late 2024 and 2025. CAS Cold Atom (Zhongke Kuyuan) achieved China’s first commercial deployment of a neutral atom system and the country’s first overseas export. MatriQ is likely the commercialisation arm of a world-record USTC atom array experiment. Buchou Quantum from Fudan has reported a 1,000-qubit prototype. And Liangyi Wanxiang is emerging as Beijing’s own neutral-atom contender. The modality’s appeal long coherence times, room-temperature atomic source preparation, optical tweezer programmability mirrors the enthusiasm driving QuEra, Atom Computing, and PASQAL in the West. CAS Cold Atom  中科酷原 Neutral Atom · Wuhan · CAS spinout 2020 · Hanyuan-1 100-qubit · ~100M RMB China Mobile round · First commercial deployment + Pakistan export Oct 2025 Neutral Atom Funded CAS Cold Atom (also known as Zhongke Kuyuan 中科酷原) is China’s first neutral atom quantum computing company to achieve commercial deployment, delivering its Hanyuan-1 100-qubit neutral atom system in October 2025 to a China Mobile subsidiary and completing an export order to Pakistan the first confirmed overseas commercial sale of a Chinese neutral atom quantum computer, worth 40M+ RMB combined. The company subsequently closed a ~100 million RMB strategic financing round funded exclusively by China Mobile Chain Leader Fund. Founded in 2020 as a spinout of CAS’s Innovation Academy for Precision Measurement Science and Technology in Wuhan, the company draws on nearly twenty years of cold atom research at CAS. Hanyuan-1 fits within three standard equipment racks and operates at room temperature, eliminating cryogenic infrastructure. The Hanyuan-1 deployment involved Wuhan University, Wuhan Institute of Quantum Technology, HUST, and Wuhan Optics Valley Information Optoelectronic Innovation Center, with over 50 universities and companies joining the application development programme. A cloud platform for atomic quantum computing, co-developed with the Wuhan Quantum Institute, gives external access to the hardware. The company is also developing a portable atomic quantum gravimeter for geophysical sensing and navigation a dual-use product line that positions it similarly to Infleqtion in the US, which combines quantum computing and quantum sensing. Hanyuan-2 is in active development, targeting further improvements in system architecture, qubit count, and coherence. With commercial customers, a confirmed overseas export, and China Mobile as a strategic backer, CAS Cold Atom / Zhongke Kuyuan is the most commercially advanced neutral atom company in China. MatriQ  原子矩阵 Neutral Atom · Full-stack optical tweezers · Seed Nov 2025 · World-record atom array pedigree Neutral Atom Seed MatriQ is a full-stack neutral atom quantum computing company using dynamic optical tweezer arrays. The company completed its Seed round in November 2025 with investors including L2F Light to Future (which also acted as full-process incubator), Qiancheng Capital, and Oriza Seed. Though deliberately vague in its public communications, MatriQ is widely believed to be the commercial spinout of the USTC-Shanghai AI Lab team that set a world record in atom array quantum computing in 2024. The 2024 paper that likely underpins MatriQ’s technology demonstrated world-record performance in a neutral atom qubit array using optical tweezers, and was highlighted by Pan Jianwei’s group as a significant step toward practical neutral atom quantum computing. The company has stated its core team comes from renowned universities and has successfully developed a neutral atom quantum computing prototype with internationally advanced performance indicators. MatriQ’s seed-stage status makes it one of the earliest-stage companies in this guide, but the technical pedigree suggested by its probable USTC origins gives it an unusually strong scientific foundation. Buchou Quantum  不筹量子 Neutral Atom · Shanghai · Fudan spinout · 1,000 atomic qubit prototype · Angel Dec 2025 Neutral Atom Angel Buchou Quantum is a full-stack neutral atom quantum computing company founded as a Fudan University spinout in Shanghai, with a reported 1,000-qubit neutral atom prototype using optical tweezers to trap Rubidium and Cesium atoms. It completed an Angel round of tens of millions of RMB in December 2025, led by CAS Star with participation from Fudan’s investment arm Furong Investment and Oriental Fortune Capital. The company originated through Shanghai’s “Grant-Investment Linkage” (拨投联动) policy: investors were invited to evaluate government-funded research milestones, were impressed enough to encourage the team to commercialise, and then backed the resulting company. That policy mechanism is notable because it represents a more market-sensitive variant of China’s usual top-down funding model, using VC judgment to filter which academic projects merit spinout support. Buchou Quantum’s founders are described as having a particularly strong quantum algorithm background in addition to hardware expertise a combination that matters for neutral atom systems, where hardware and software co-design is critical for realising the theoretical advantages of the modality. Liangyi Wanxiang  两仪万象 Neutral Atom · Beijing · Early Stage Neutral Atom Early Stage Liangyi Wanxiang (两仪万象) is a Beijing-based neutral atom quantum computing startup, confirmed as an active company by its appearance at the Beijing Quantum Industry Ecological Innovation Conference in August 2025, where it was listed alongside Hyqubit (trapped ion), ArcLight Quantum (software), QBoson (photonic), and Coherent Technology (superconducting) as one of five representative Beijing-based quantum enterprises. Its presence signals Beijing’s intent to have a domestic neutral atom contender in its own cluster, rather than ceding the modality entirely to companies in Wuhan (CAS Cold Atom) and Shanghai (Buchou Quantum, MatriQ via USTC). Limited public information is available about Liangyi Wanxiang’s academic origins, team, technical approach, or funding. The neutral atom sector in China has seen very rapid formation since late 2024, and Liangyi Wanxiang appears to be among the earliest Beijing-based entrants. Further details are expected as the company moves toward early fundraising and prototype announcements. Beijing’s “Quantum Ten” municipal support policy and the dedicated BAQIS research infrastructure position any Beijing-based neutral atom company to benefit from city-level resources alongside Hefei’s more established national quantum labs. Quantum Communications & QKD China’s lead in quantum communications is not marginal it is generational. The national QKD backbone network stretches more than 12,000 kilometres, incorporates 145 backbone nodes, covers 17 provinces and 80 cities, and integrates two operational quantum satellites. No other country has anything close to this deployed infrastructure. QuantumCTek is the core hardware supplier that made it possible. Guoke Quantum is the CAS-affiliated network operator that actually builds and runs the provincial backbone infrastructure. Qasky and LuxQuanta serve the secondary layers of enterprise and metropolitan deployment. Kyushu Quantum, China’s first listed quantum company (NEEQ 2016), stands as both a pioneer and a cautionary tale: it predated QuantumCTek’s STAR Market IPO by four years but has since fallen into severe financial distress. QuantumCTek  国盾量子 QKD + Quantum Computing · Hefei · STAR Market Listed (688027) · US Entity List · China Telecom-controlled QKD Listed Entity List QuantumCTek is China’s only publicly listed pure-quantum company, the commercial engine behind the world’s largest quantum communication network, and the organisation that has done more than any other to transform quantum key distribution from a laboratory experiment into deployed national infrastructure. It is also one of the first quantum entities added to the US export control entity list a designation that has shaped both its strategy and the entire Chinese quantum self-sufficiency drive. Founded in 2009 as a spinout from Pan Jianwei’s group at USTC, QuantumCTek listed on the Shanghai STAR Market in 2020 as the first quantum technology stock in China. Pan Jianwei’s research group is also behind the Micius quantum satellite (the world’s first), the Jinan-1 microsatellite, the Beijing-Shanghai quantum communication backbone (completed 2020, 2,000 km), and the Zuchongzhi superconducting quantum computing series. QuantumCTek is the commercial vehicle that turns this research output into products: QKD terminal equipment, quantum network management systems, quantum random number generators, and increasingly, superconducting quantum computing hardware and measurement and control systems. In January 2025, China Telecom Quantum Group assumed a controlling stake, integrating QuantumCTek into state telecommunications infrastructure. QuantumCTek reported H1 2025 revenues of CNY 121 million (approximately $17 million), up 75% year-on-year a run rate comparable to IonQ for a similar period. Notably, quantum computing revenue contributed CNY 56 million (284% growth), with the company exporting a 25-qubit superconducting computer internationally and installing 100+ qubit platforms domestically. QKD-related revenue was CNY 52 million. In May 2025, QuantumCTek and China Telecom Quantum launched what they described as the world’s first commercial QKD+PQC hybrid security system, combining quantum key distribution with post-quantum cryptographic algorithms in a single deployed product. In November 2025, the company released China’s first high-performance PQC chip, positioning QuantumCTek as the only organisation delivering both QKD hardware and domestically produced PQC silicon. The same period saw the demonstration of a 1,000 km quantum-encrypted voice call over the national backbone network. The company is also pursuing domestic dilution refrigerator manufacturing through the Anhui Quantum Computing Engineering Research Center, having started factory production of the EZ-Q Fridge in 2024. QuantumCTek’s addition to the US entity list in 2021 cut off access to US components and investment but simultaneously created the political mandate and government funding to develop Chinese alternatives. The Pan Jianwei connection: Understanding QuantumCTek requires understanding that the company is essentially the productisation arm of the most consequential quantum research group in China. Pan Jianwei, a member of the National People’s Congress, has been China’s most effective scientific advocate for quantum funding. His group produced the Micius satellite, the 12,000 km QKD network, multiple photonic quantum advantage results, and the Zuchongzhi superconducting series. QuantumCTek converts that pipeline into revenue with CAS and USTC as both IP source and anchor shareholder. Qasky  安徽问天量子科技 QKD Equipment · Wuhu, Anhui · CAS-affiliated · Founded 2016 · Cryptography terminals and network security QKD/Comms Private Qasky (Anhui Qasky Quantum Technology) is a CAS-affiliated QKD equipment manufacturer founded in 2016 in Wuhu, Anhui Province. Its co-founders include Cai Jiren, Guo Guangcan, and Han Zhengfu, established quantum scientists from USTC’s quantum optics tradition. The company commercialises quantum cryptography research from CAS, producing QKD communication terminals, network switching and routing equipment, core optoelectronic devices, random number generators, and integrated quantum information security systems. Qasky was established with 50 million RMB in registered capital, jointly funded by Wuhu Construction and Investment and USTC. It has built a provincial quantum security project technology research centre and an academician workstation in Hefei, making it part of the Hefei quantum ecosystem despite its Wuhu headquarters. Its customer base spans government, finance, defence, and telecommunications the core sectors driving China’s quantum communications procurement. Qasky is one of the secondary suppliers in China’s national QKD network deployment, complementing QuantumCTek’s dominant position in backbone infrastructure with provincial and enterprise-level equipment. The company’s deep CAS connections and USTC academic support give it strong institutional backing typical of China’s quantum commercialisation model. LuxQuanta Technologies QKD Systems · China · Founded 2017 · National quantum comms network infrastructure QKD/Comms Private LuxQuanta Technologies is a Chinese quantum communication company founded in 2017, developing quantum key distribution systems and quantum secure networks. The company provides QKD equipment and quantum communication infrastructure for China’s national quantum communication networks, participating in China’s strategic programme to build quantum-safe communications across government and commercial sectors. LuxQuanta operates in the same QKD equipment space as QuantumCTek and Qasky, contributing hardware for the secondary and provincial layers of China’s QKD network rollout. The company is part of the broader ecosystem of suppliers that emerged as China’s state procurement of QKD equipment scaled from the national backbone (dominated by QuantumCTek) to regional and enterprise deployments. Its 2017 founding places it among the first generation of Chinese quantum communications startups, predating the acceleration of government procurement that has characterised the sector since 2020. Kyushu Quantum  九州量子 QKD Pioneer · Hangzhou · NEEQ Listed 2016 (837638) · China’s first listed quantum company · Financial distress QKD/Comms NEEQ Listed China’s first listed quantum company (NEEQ 837638, January 2016), predating QuantumCTek’s STAR Market IPO by four years. Founded 2012 in Hangzhou; peak valuation approached ¥30 billion CNY. A criminal dispute with QuantumCTek and a collapsed partnership with Switzerland’s ID Quantique inflicted lasting reputational damage. By 2024, revenue had fallen ~75% to ¥13.75 million, headcount dropped to 49 (29 R&D), and NEEQ issued a formal inquiry letter questioning its ability to continue operations. Pioneer and cautionary tale in equal measure. Guoke Quantum  国科量子通信网络 QKD Network Operator · Shanghai · ~$230M raised · CAS-affiliated · National backbone infrastructure QKD / Comms Private Guoke Quantum is not a hardware company. It is a CAS-affiliated QKD network operator and integrator: the entity that builds and runs China’s provincial quantum communication backbone networks using QuantumCTek equipment and provincial government capital. Where QuantumCTek makes the boxes, Guoke Quantum lays the fibre and operates the infrastructure. Founded in Shanghai in November 2016 under the Chinese Academy of Sciences, the company has built subsidiaries in Guangdong, Henan, Beijing, and Hubei, each targeting regional quantum network construction. Its most documented deployment is the Hubei provincial quantum backbone network, introduced in 2018 in partnership with Hubei Communications Investment Group: over 1,700 km of fibre, 3 backbone stations in Wuhan, Jingzhou, and Yichang, and 22 relay stations covering 10 cities and prefectures. The company has since built out similar structures in other provinces. Alongside network operations, Guoke Quantum co-developed a quantum security chip (CCM3310SQ-T) with Suzhou GuoXin Technology and has filed 87 patents. The $230M in funding from 16+ investors — including China Cable, Hongshan Capital, Henan Investment Group, and Infinity Group — reflects the infrastructure-scale capital required for national network construction rather than conventional startup financing. This is a roads-and-rails play, not a product startup. QuantumCTek vs Guoke Quantum — QuantumCTek makes QKD hardware and sells it to network operators. Guoke Quantum is one of those network operators, building and running the actual provincial fibre infrastructure. The two companies cooperate; Guoke Quantum is a major QuantumCTek customer and a key node in how the national QKD backbone physically gets built outside of the BSBN trunk line.

QBoson, TuringQ, and Guizhen Silicon Quantum are each building distinct photonic approaches; QBoson broke ground on China’s first dedicated photonic quantum computer factory in August 2025, and Guizhen released China’s first domestic universal programmable optical quantum computer at the November 2025 Hefei conference. The technology is at an earlier stage than superconducting hardware globally, but the manufacturing and scale-up advantages of operating at room temperature are particularly relevant for a country under export controls on cryogenic equipment. QBoson  玻色量子 Photonic Quantum Computing · Beijing (factory: Shenzhen; labs: Suzhou, Nanjing) · Series A++ (Oct 2025) · 1,000-qubit system · China’s first photonic QC factory Photonic Private QBoson is China’s leading photonic quantum computing company and the organisation most aggressively pushing coherent light-based quantum hardware from research prototypes into manufactured products. In April 2025 the company released its third-generation coherent optical quantum computer with approximately 1,000 computational qubits a significant milestone in photonic qubit scale operating stably at room temperature for more than 12 hours per day. China’s CAICT issued a technical verification report confirming nine performance indicators including qubit count, coupling density, coupling precision, and application-level computational performance. Founded in late 2020 by Wen Kai and Ma Yin, QBoson focuses on “coherent quantum computing” using correlated photon pairs generated by a proprietary CMOS-based electronic-photonic chip. The architecture is not universal gate-based computation; it is purpose-built for combinatorial optimisation and AI workloads, specifically implementing a quantum Boltzmann machine framework. QBoson’s strategic pivot in 2025 is toward “Quantum + AI” applications: the Kaiwu SDK targets AI acceleration, drug discovery, biopharma simulation, logistics, and financial scheduling with a particular focus on positioning quantum Boltzmann machines as a complement to classical neural network training. The company has partnered with the Postal Savings Bank of China and China Mobile to deploy quantum algorithms for bank teller scheduling and logistics optimisation, among the first reported commercial quantum deployments in Chinese financial services. Labs have been established in Suzhou and Nanjing in addition to the Shenzhen manufacturing facility, creating an eastern China presence spanning the Yangtze River Delta and Pearl River Delta. QBoson completed a multi-hundred-million RMB Series A++ round in October 2025 its sixth public funding round since founding co-led by Huade Tech Innovation and Nanshan Strategic Emerging Investment with participation from China Mobile’s investment fund and Tsinghua Holdings. The Shenzhen photonic quantum factory, groundbreaking in August 2025, is designed to produce dozens of photonic quantum computers annually across three dedicated divisions for module development, full-system production, and quality control. QBoson is listed on China Mobile’s Wuyue quantum cloud platform and reports over 68 million cumulative cloud computing invocations, users from over 900 universities, and more than 10,000 registered developers on its quantum computing developer community. Room temperature as strategic advantage: Photonic computing’s lack of cryogenic requirements is not just a technical property in China’s context it is supply-chain independence. Every superconducting quantum computer requires dilution refrigerators capable of reaching 15 millikelvin. A photonic system that operates at room temperature eliminates this vulnerability entirely. Whether coherent photonic systems can achieve the error rates required for general-purpose computation remains an open question globally, but QBoson’s commercial traction in specialised optimisation and AI workloads suggests its near-term case does not depend on answering it. TuringQ  图灵量子 Integrated Photonic Quantum · Shanghai · Silicon photonics chips · One of 2 Chinese firms in 2025 global top-80 list Photonic Private TuringQ is Shanghai’s most globally recognised quantum computing startup, one of only two Chinese companies included in the 2025 Quantum Insider list of the world’s 80 top quantum computing companies a distinction that reflects both its technical credibility and the relative scarcity of globally competitive Chinese quantum firms outside the Hefei ecosystem. Founded in 2021 by researchers with backgrounds in silicon photonics and quantum optics, TuringQ develops integrated photonic quantum chips fabricated in standard CMOS-compatible silicon photonics processes. The core bet is that silicon photonics a mature fabrication technology used in high-speed telecom transceivers can serve as the platform for scalable quantum photonic processors, leveraging the same foundry infrastructure that makes classical photonic chips manufacturable at scale. The approach targets linear optical quantum computing and boson sampling applications, where photonic platforms have historically demonstrated quantum advantage most convincingly (Jiuzhang, the USTC photonic processor, demonstrated quantum advantage in boson sampling in 2020 and 2021). TuringQ’s silicon photonics route is distinct from QBoson’s coherent computing architecture, representing a second technical bet within China’s photonic quantum computing cluster. TuringQ has attracted backing from Shanghai-based investors and strategic research partnerships with institutions in the Yangtze River Delta region. Its global recognition alongside only QBoson among Chinese companies in the top-80 global quantum computing list compiled by industry analysts reflects international acknowledgment of its technical approach even as its commercial profile remains substantially more limited than Hefei’s superconducting champions. Guizhen Silicon Quantum  硅臻量子 Integrated Silicon Photonic QC · Hefei · USTC spinout · 3 funding rounds · 国芯科技 (688262.SH) 11.5% stake · Nov 2025: first domestic universal optical QC Photonic Private Guizhen Silicon Quantum (合肥硅臻芯片技术有限公司) is a Hefei-based photonic quantum computing company founded in 2020 as a spinout from USTC’s CAS Key Laboratory of Quantum Information, with Chief Scientist Prof. Ren Xifeng, a leading figure in quantum nano-optics and silicon photonic quantum chips. At the November 2025 Quantum Technology and Industry Conference in Hefei, Guizhen became the first Chinese company to release a domestic universal programmable optical quantum computer based on silicon photonic integrated chips a system built on photons as qubit carriers, with high-speed path-encoding chips and multi-channel entanglement source chips that are already in volume production. The system demonstrated 4-qubit operation with operational fidelity above 99.4%, cloud-accessible via a public platform, and targeting general-purpose quantum algorithm execution across optimisation, AI, simulation, and information security applications. Guizhen’s technology route is distinct from QBoson’s coherent Ising machine approach: it targets universal gate-based optical quantum computing using integrated silicon photonics, a platform that in principle leverages the same CMOS-compatible manufacturing infrastructure that makes photonic transceivers manufacturable at telecom scale. The company’s core chip competencies entanglement source arrays and path-encoding circuits follow the linear optical quantum computing architecture and are compatible with boson sampling benchmarks of the kind used by USTC’s Jiuzhang series. The 2024 quantum computer prototype was certified as a Hefei Municipal First-of-Kind Major Technical Equipment, an official milestone for local government co-investment. Guizhen has completed three rounds of funding since founding, with investors including Guoxin Technology (国芯科技, STAR Market: 688262.SH), which holds an 11.46% equity stake via strategic investment. This makes Guizhen the only Chinese quantum computing startup with a listed-company strategic shareholder that is itself a semiconductor company, providing both capital and supply-chain credibility for chip-level integration. The USTC spinout pedigree links Guizhen directly to Pan Jianwei’s ecosystem, even though its technology route diverges from QuantumCTek (QKD) and Origin Quantum (superconducting). The CMOS photonics bet: Guizhen’s wager is that integrated silicon photonics not bespoke quantum optical benches is the correct manufacturing substrate for scalable photonic quantum computing. Standard silicon photonics foundries can fabricate waveguides, beamsplitters, and phase shifters with sub-micron precision at commercial scale. If the error rates achievable in CMOS-foundry photonic circuits can reach fault-tolerant thresholds, Guizhen’s approach would be manufacturable without the custom cleanroom infrastructure that limits every other quantum hardware modality. The November 2025 system is a long way from that threshold, but the fabrication roadmap is credible. Full-Stack & Accessible Systems SpinQ occupies a unique position in the Chinese quantum landscape: it is the only major Chinese quantum company with a genuine global commercial footprint, generating revenue from product sales to universities and research institutions across more than 40 countries. Its dual-track strategy low-cost NMR education systems alongside industrial-grade superconducting hardware gives it both near-term cash flow and long-term positioning in the superconducting computing market. SpinQ Technology  量旋科技 NMR Education + Superconducting · Shenzhen · Series C · 200+ universities · 40+ countries · Revenue 2x+ YoY 2025 Full-Stack Pre-IPO SpinQ Technology is the most commercially mature quantum computing company in China by revenue and international reach generating 50+ million RMB in 2024 revenues, growing orders and revenue by more than 130% in 2025, and selling into over 200 institutions across more than 40 countries through a dual product strategy that no Western competitor has tried to replicate. Founded in 2018 by Xiang Jingen, a Tsinghua physics PhD with postdoctoral research at Harvard, SpinQ launched the world’s first programmable desktop NMR (nuclear magnetic resonance) quantum computer, the Gemini, in 2020 a compact, maintenance-free 2-qubit device designed for teaching and research access without specialist infrastructure. The Gemini and its successors (Triangulum, Gemini Lab) have become the standard hands-on quantum education platform at universities from Singapore’s SUTD to Vassar College in the US. These NMR systems, which work on magnetic resonance principles rather than superconducting circuits, require no cryogenics and no cleanroom, making them uniquely accessible for institutions without quantum engineering infrastructure. In 2023, SpinQ became the first Chinese company to export a superconducting quantum chip to the Middle East. The industrial-grade track is the Ursa Major series of superconducting quantum computers, which SpinQ develops with full-stack independence: its own chip design using the proprietary “Shaowei” superconducting chip (released 2023), its own control systems, and its own SpinQit programming framework. The superconducting-to-NMR revenue ratio has shifted to approximately 6:4 as multiple Ursa Major systems are delivered domestically and internationally. SpinQ completed a Series C round from investors including Longli Technology, Yida Capital, and Jingkai Capital in 2026, and is positioned for a Hong Kong or Shenzhen exchange IPO within the next 18 months. The CEO acknowledges US maintains roughly a three-year lead in quantum computing development a rare public admission of the competitive gap from a Chinese quantum executive. The education flywheel: SpinQ’s education business is not a side project funding the real work it is the strategic moat. Every undergraduate who learned quantum computing on a Gemini system is familiar with SpinQ hardware and software. Universities that bought Gemini units often return for industrial-grade Ursa Major systems. This creates a customer pipeline that competitors trying to sell superconducting hardware directly into enterprise or government cannot replicate. The 200+ institutional customers across 40+ countries are also a global distribution network that Chinese superconducting hardware competitors entirely lack.
