It plans to build a network of quantum computers accessible via the cloud and targets rapid near-term growth as researchers begin using its hardware on a larger scale.The company partners with Microsoft (MSFT -1.12%), Amazon (AMZN -1.01%) Web Services (AWS), and Alphabet's (GOOG -0.78%) (GOOGL -0.83%) Google Cloud. Japanese telecommunications company and tech investor SoftBank Group (SFTBF +3.22%) has also invested in IonQ.SoftBank is partnering with IonQ to bring quantum computing power to the many other tech companies in its portfolio. While its older Aria system has been available via AWS since 2023, the company is now rolling out its next-generation 100-qubit system, Tempo, designed to achieve commercial advantage for enterprise workloads.IonQ has generated minimal revenue so far and is not yet profitable. It will need to continue spending heavily to develop its products and business for at least a few more years. However, it reported a $470 million backlog of orders in the first quarter of 2026. That's a substantial start, up 550% from the year-ago period.Investing in this start-up is still a speculative play, despite its improving financial prospects. If IonQ's research efforts are successful, the stock could be a profitable way to invest in quantum computing, but investors should act with prudence. This is still a start-up business, and its valuation is often sky-high.2. MicrosoftThe software titan researches and develops a wide range of technologies, and quantum computing is no exception. Quantum computers need special refrigeration, superconducting chips, and highly specific software, all of which Microsoft is developing in its labs. Microsoft also offers researchers access to quantum computing services via its massive cloud platform, Azure.ExpandNASDAQ: MSFTMicrosoftToday's Change(-1.13%) $-4.56Current Price$397.73Key Data PointsMarket Cap$3.0TMarket cap calculated using publicly traded shares outstanding only.

The unit merged with Cambridge Quantum Computing in 2021 to form Quantinuum, which operated as a Honeywell subsidiary until the 2026 IPO. Honeywell remains the controlling shareholder and continues to supply hardware and infrastructure to the company.The company builds trapped-ion quantum computers and the software stack that runs on them. Customers include JPMorgan Chase (JPM +1.60%), Amgen (AMGN -0.11%), and Honeywell itself, which uses Quantinuum's tech in some of its own products.The financials tell an early-stage business story, though. Quantinuum generated $30.9 million in revenue for 2025 against a $192.6 million net loss. The company had $677 million in cash as of March 31, 2026.With Honeywell's backing and years of research results, Quantinuum fills a gap in the quantum computing industry. It stands between the risky pure-play names and the tech heavyweights folding quantum research into their larger business models.For investors who want a direct quantum bet with some adult supervision, this is the only option available so far.7. IBMIBM (IBM -0.89%) has its own quantum computing chips and systems available for commercial use through its IBM Quantum business unit. More than 210 research organizations and companies, ranging from financial services businesses to automakers to energy producers, use IBM's quantum computing services.ExpandNYSE: IBMInternational Business MachinesToday's Change(-0.82%) $-1.75Current Price$211.25Key Data PointsMarket Cap$200BMarket cap calculated using publicly traded shares outstanding only.

However, the regulatory landscape shifted dramatically in May 2026 when the U.S. Department of Commerce announced a $2 billion funding injection under the CHIPS and Science Act to secure domestic quantum infrastructure.Rigetti walked away with a letter of intent for as much as $100 million in federal incentives. That's a significant safety cushion that should give Rigetti more time to deliver business results.You should still be careful with Rigetti's shares, though. With promising research projects but minimal business operations, the stock often looks overheated.9. D-Wave QuantumInstead of separate ions, D-Wave's (QBTS +6.37%) systems rely on superconducting loops with strong magnetic fields. These annealing circuits work together in groups, gaining pattern-finding power from the interactions among their energy states.ExpandNYSE: QBTSD-Wave QuantumToday's Change(6.22%) $1.04Current Price$17.76Key Data PointsMarket Cap$6.2BMarket cap calculated using publicly traded shares outstanding only.

But the annealing systems can also grow incredibly powerful under the right circumstances. In particular, annealing circuits can provide a better starting point for quantum gate calculations.So, D-Wave's quantum computers could become a standard addition to more ambitious quantum gate systems. That's a unique strategy. D-Wave's stock is richly valued despite lackluster revenues and negative profit margins. Be careful with these financially unstable specialists, dear investor.How to buy quantum computing stocksOpen your brokerage account: Log in to your brokerage account where you handle your investments.

You'll notice that some computing methods take a long time to deliver specific results, while others quickly deliver estimates in the right ballpark. There are also software complexities, ways to connect classical digital computers to their quantum cousins, and many methods and materials used to perform quantum-based calculations. Understanding these nuances will help you make smarter investments, even in this early stage of an emerging technology.There are a few quantum computing pure-play companies. Some, such as D-Wave Quantum (QBTS +6.37%) and Rigetti Computing (RGTI +6.98%), went public in the early 2020s.Their stocks soared in 2024 as basic quantum computing technology took a major step forward. Further tech breakthroughs in 2025 kept the momentum going, lifting the quantum specialists to new highs in October.Several companies developing software for quantum computers exist, such as security software start-up Arqit Quantum (ARQQ +3.20%) and integrated hardware and software company Quantum Computing (QUBT +2.84%). A quantum computing exchange-traded fund (ETF), Defiance Quantum ETF (QTUM +2.79%), is also available, providing broader exposure to this nascent industry.Many larger tech businesses and semiconductor designers are also increasing their activity in the quantum realm.Should you invest in quantum computing stocks?At this point, there is no established leader in quantum computing. Dozens of companies, including several tech giants, are researching its potential and experimenting with real-world uses. Developing quantum hardware that accurately performs computations and meets reasonable return-on-investment thresholds is still ongoing.So, there are no clear long-term winners to invest in at this point, apart from the established tech giants who can treat quantum computing as a promising side gig. Smaller quantum computing experts such as D-Wave, Rigetti, and IonQ might deliver great long-term returns -- but they also face significant risks without a financial safety net.All things considered, quantum computing is best approached with care. Established winners and exchange-traded funds (ETFs) can limit your risks, and direct bets on the smaller experts in this field should be fairly small. Those are high-risk, high-reward long-term bets.Related investing topicsBest Quantum Glass Battery Stocks to Buy in 2026Batteries are essential for the energy transition.
