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.
An October 14 study models nonradiative energy loss in diamond and silicon-carbide defects. Better calculations can clarify the physics without claiming a new device or quantum-computing speed record.
Calculations suggest atomic vacancies could help shape topological electronic phases. The October journal milestone builds on a March preprint; a working device remains undemonstrated.
A new theory paper clarifies what correlations can establish and which ambiguities remain inside device-independent certification.
A local-probe NMR experiment reaches journal publication, with a clear boundary between spectroscopy and a working quantum register.
The accepted GaAs study reports a 4.05 ns gate and makes the supporting feedback overhead explicit.
The Kaggle challenge uses kickmix to seek smaller quantum circuits. Randomized tests check approximate correctness under stated conditions.
Telefónica and IQM plan an education and research installation at UPM. Delivery and hands-on access are the milestones still to come.
An accepted physics paper uses a qubit probe to test nonclassical behaviour. Its conservation-law and measurement conditions are essential to the result.
A Bechtle/IQM agreement supplies cloud quantum resources to DLR’s initiative, with classical support for hybrid work.
Black Kite has announced new third-party risk controls. Observable encryption signals are a starting point, not a complete security verdict.
Aalto’s Coherence Quantum spinout has confirmed seed funding. The engineering promise is a less burdensome route between control electronics and cold qubits.
A Northwestern experiment brings a positron under quantum control. The next question is whether matter and antimatter match as precisely as physics expects.
New measurement protocols aim to reveal motion as well as position. They work within quantum uncertainty, not around it.
Quandela and Quanova have announced a deployment at Quang Trung University. Delivery and practical access remain the milestones to watch.
Newly published transport measurements probe an unusual boundary response. They do not yet establish a working topological qubit.
IBM’s latest earnings describe its wider business. The release does not isolate quantum sales, making the distinction essential for readers tracking the sector.
A UK project will develop batch packaging for ion traps. Repeatable manufacturing results will show what the funding delivers.
The October announcement describes an operating layer for hybrid computing services. Early access and integration claims remain separate from measured quantum performance.
A peer-reviewed result strengthens bit-flip protection while keeping the comparison with phase errors visible.
A new cooperation framework links Q-STAR and VTT. Concrete projects will show what the partnership delivers.
The city is funding NYU's planned QFab facility and will receive a defined share of university proceeds. The details matter more than the headline percentage.
An ETH Zurich spin-off connects quantum software to laboratory signals. Its specifications reveal why the whole feedback loop matters.
Optical quantum-state smoothing improves retrospective estimates, with the assumptions about missing information kept explicit.
