IBM unveiled the third generation of its Nighthawk quantum processor, r3, targeting 10,000 quantum operations on 520 qubits, and plans to link two chips into a 1,040-qubit system in 2027. All figures are IBM’s own targets.
The bipartisan Commission on U.S. Quantum Primacy released its first preliminary report, proposing a national quantum foundry, NIST-led benchmarks and a faster post-quantum cryptography transition, but left budget figures to a final report in 2027.
Diraq has begun running a silicon spin quantum computer at an Equinix data center in Sydney. The 8-qubit system draws under 20 kW and targets 256 qubits within a year, but no accuracy metrics have been released.
Physical Superintelligence (PSI) claims it proved the Aaronson-Ambainis conjecture, open since 2008, using an unreleased Anthropic model. It cites Lean verification, but peer review has yet to take place.
China’s photonic quantum computer Jiuzhang 4.0 has won a World Internet Conference Leading Science and Technology Award. We look at what its 3,050-photon experiment means, the classical-algorithm debate and its limits.
IonQ reported third-quarter revenue of $173.8 million and Quantinuum $9.1 million. We compare how acquisitions and error-correction performance set the two listed quantum companies apart.
D-Wave has improved its Stride hybrid solver. The company says it beat the previous version’s 120-second solutions in 15 seconds and came within 0.02% of the best solution on traveling salesman problems with up to 10,000 locations.
