Source-linked quantum computing news and analysis on hardware, research, applications, post-quantum security, business and policy.
Publication date where available; source report or sources-checked date otherwise.
A noisy hardware demonstration recovers broad thermodynamic features using a known energy grid and explicit post-processing.
A new optimization benchmark separates solution quality from optimality certification and finds no quantum advantage in its tested protocols.
A laboratory demonstration uses variational optimization for polarization protocols. Deployed fiber networks remain future work.
ML-DSA support starts with 1Password 8.12.44. Compatible websites are required and creation still has iOS and native macOS autofill limits.
A Physical Review Letters study models neighboring-layer exciton shifts and explains why a small correction can matter when comparing signals.
A mathematical protocol narrows a certified fidelity interval by choosing measurements adaptively. Structured cases can benefit, while the hardest cases still require full coverage.
A transformer decoder reaches journal publication with promising surface-code simulations. The headline percentage describes code-capacity noise, not a hardware gate-error allowance.
An October 22 memorandum covers quantum-inspired and quantum-safe exploration through feasibility studies, sandbox work and potential pilots.
A model uses resonator interference to suppress unwanted mixing and compensate dispersion. Fabrication tolerances and measured output remain the next engineering questions.
A theoretical protocol links projected ensembles to the resource-generating power of quantum dynamics. An experimental assessment would still need its assumptions and costs checked.
The programme allocates equipment spending from existing university research budgets. Sensor performance and commercial delivery remain future tests.
A new framework controls false positives in tests of nonstabilizerness under explicit sampling assumptions. The result is a certification method, not a hardware advantage.
A new similarity-estimation proposal links a modified SWAP test to simulated interference images. Magnetic-field sensing remains a prospective use.
The official assessment proposes a 2027–2031 initiative focused on domestic strengths and international supply chains. The figures describe 2025 investment.
Operation FlashHole illustrates an unexpected use for ML-KEM. The vendor’s disclosure concerns malware delivery, with activity evidence dating to July 2025.
The UK programme’s new Phase 1 report records seven testbeds and outlines the evaluation work due to finish in Q2 2027.
New Database 19c guidance makes client compatibility and the negotiated connection central to the migration.
Qblox reports round trips below 4.0 microseconds for RTX PRO 6000 Blackwell and below 7.2 microseconds for DGX Spark.
Germany’s QSolid consortium reports a tested 10-qubit system available to users, with a larger prototype still under evaluation.
An analytical model examines when dissipative charging produces extractable work, with frequency detuning and interaction strength shaping the result.
A model inspired by bacterial light harvesting reaches journal publication, with separate optima for power and extractable work.
A historical-cipher study examines the acceptance rule inside Grover search. Its projected advantage is over random search, with no modern encryption break.
Initial experiments have begun at IQCC. Decoder integration remains ahead, and the company says real-time correction has not yet been demonstrated.
The proposed arrangement covers capacity and services associated with 12 WISeSat.Space satellites. Technical qualification and definitive agreements remain ahead.
