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 simulated trapped-ion architecture kept decoding delay below 12% across three compiled workloads, but no fault-tolerant quantum computer ran the experiment.
A new Japanese roadmap spells out the light sources, detectors and control hardware that must improve before photonic systems can scale.
Chemicals, batteries and pharmaceuticals are among the clearest candidates for early gains. Their breakthroughs could reach you through everyday products.
A new Delft unit will combine European components into complete superconducting quantum computers and develop a repeatable integration process.
Superconducting rails help detectors reach 0.1 millimetres in width while reducing false signals—a useful step toward larger optical sensors.
A superconducting design divides storage and interaction between two coupled modes, with faster gates predicted in simulations.
A planned Danish foundry would give quantum-hardware teams another place to manufacture their chips.
The funding opportunity asks teams to show how an entire application benefits, with a defined end user and credible classical comparisons.
Princeton-led MARQUIS will bring materials science and semiconductor processing to the Josephson junction, a core superconducting-qubit component.
The newly inaugurated quantum computer is operational, with qualification, broader access and supercomputer integration still progressing.
Nighthawk r2 attacks the pause between runs. Its three headline numbers describe different things, and should stay that way.
The C$195 million federal commitment supports a C$893 million project. Follow funding, process qualification and module acceptance separately to see what the manufacturing program delivers.

Box-shaped cryostats offer shorter interconnect paths and more wiring room for future multi-processor quantum systems.
A research workflow trains a transformer to propose molecular state-preparation circuits, with selected circuits tested on Helios hardware.
The companies report a 65.3% reduction in peak location-registration signals and a 7.0% reduction in paging signals.
A common library of ten optimization problem classes gives quantum and classical approaches comparable tasks and public results.
A photonic integrated circuit produced four rubidium-atom traps, with an approximately 27.5-second lifetime reported by the company.
RFC 10024 specifies three combinations of ML-KEM and elliptic-curve key agreement at Proposed Standard maturity.
A Nature experiment reports an approximately 500-nanosecond entangling gate that largely preserves detectable photon-loss errors.
Their research combines classical preprocessing and problem decomposition with quantum workflows to reduce the burden placed on hardware.
The companies report closing a transaction that brings US semiconductor fabrication and packaging capacity into IonQ's organization.
The revised experiment used 76 physical qubits. Built-in checks let the team estimate how closely the retained runs matched the intended state.
