While using the Stim getting_started.ipynb notebook , there is a picture as an output for "dem.diagram("matchgraph-svg") , what exactly the horizontal edges and the vertical edges of the output refer …
Within a lattice of interacting qubits, a surprising persistence of quantum order has been observed even as entanglement fades. Previously, detecting quantum behaviour in transport models demanded str…
Until recently, systematic error analysis lagged behind the rapid development of quantum hardware. Now, a comprehensive review advocates applying established mathematical tools, probabilistic modellin…
Calculating even simple materials’ behaviour at different temperatures has long demanded computational power that grows exponentially with complexity. Now, a new algorithm extends established techniqu…
Calculating even a simple material’s behaviour at multiple temperatures currently demands computational power that grows exponentially with its complexity. Now, a new algorithm offers a potential rout…
Quantum mining of Bitcoin demands a fleet of qubits comparable in scale to a large national grid. Calculations reveal that achieving a competitive edge, even with favourable settings, necessitates app…
Until now, the Quantum Computing Quantum Monte Carlo framework largely confined simulations to a system’s lowest energy state. This work systematically builds quantum circuits to unlock a far broader …
Previously, quantum network designs assumed perfect, grid-like connections. Now, analysis of 81 real network layouts reveals performance varies dramatically depending on physical structure, with some …
Inside a dilution refrigerator, a semiconductor quantum dot now emits photons at a rate of 2. 5 gigahertz. Previously, maintaining high indistinguishability of single photons at these speeds in the te…
Previously, the impact of surface geometry on fermion dynamics remained largely theoretical. Now, numerical results demonstrate how Gaussian and volcano-like bumps directly influence the energy spectr…
Insider Brief PRESS RELEASE — Quantum Corridor, the first inter-state quantum safe commercial communications network in North America, and Quantum Computing Inc. (“QCi”/Nasdaq: QUBT), an innovative, q…
The advance could allow these technologies to operate in deep-space probes, inside nuclear reactors, in ultrahigh vacuum systems, and at temperatures both near absolute zero and in scorchingly hot ind…
Kent Walker shares Google’s perspective on the future of privacy at IAPP Global Summit 2026.
For years, maintaining accuracy in quantum devices has demanded either pristine external references or increasingly complex internal checks. Now, a new method allows quantum systems to self-certify th…
A surprisingly precise relationship between geometrical norms holds true in up to 200 dimensions, according to new calculations. The conjecture, verified numerically, suggests a fundamental limit to h…
Previously, finding the lowest energy state of a quantum system demanded either painstaking calculation or approximation. Now, machine learning techniques predict ground-state energies even when conve…
For decades, physicists have treated identical quantum particles as though their individual existence is guaranteed by mathematical symmetry. Now, a new analysis suggests these particles are best unde…
Inside a cryostat, 72 superconducting qubits have revealed a definitive limit to the precision of atomic sensors under common noise conditions. Previously, methods to circumvent these limitations were…
A Bell-state analysis fidelity of 0. 96, achieved with a quantum photonic neural network utilising a single quantum dot, reverses a longstanding limitation in scaling these systems. Previously, buildi…
Previously, possessing the algebraic hallmarks of a harmonic oscillator guaranteed an equally spaced energy spectrum. Now, calculations reveal this is not universally true, as a quantum system confine…
Previously, identifying the boundary between order and complete disorder in quantum systems relied on indirect measures of internal state. Now, the extent to which a quantum state explores all possibl…
Insider Brief China has positioned quantum computing as a strategic national priority, allocating substantial government resources through its 14th Five-Year Plan (2021-2025) and emerging 15th Five-Ye…
Insider Brief The convergence of quantum computing and artificial intelligence has captured significant attention from researchers, investors, and media outlets. Headlines frequently suggest that quan…
