Follow quantum chips, qubits and the engineering behind them. Reports explain what was tested, what changed and what still needs work.
Publication date where available; source report or sources-checked date otherwise.
A dated component-paper spotlight separates frequency conversion from a complete network.
A wiring experiment separates measured performance from a larger system proposal.
Fresh university coverage revisits a device paper and its performance tradeoff.
A processor characterization shows why the size of each benchmark belongs in the headline discussion.
A narrow detector result explains the importance of defining an accuracy metric.
A proposed interface makes the division of work in photonic error correction explicit.
The collaboration focuses on superconducting-qubit infrastructure and training.
The preprint identifies faults at the junction of logical strings in a particular syndrome-extraction schedule.
DAWG reduces reliance on an extra correction stage in numerical tests. Its hardware latency remains an estimate.
An October 21 preprint separates state-transfer fidelity from the harder task of operating across processors.
A new theoretical circuit reaches the same direct success probability as an earlier design with half its auxiliary photons.
A laboratory demonstration uses variational optimization for polarization protocols. Deployed fiber networks remain future work.
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.
Initial experiments have begun at IQCC. Decoder integration remains ahead, and the company says real-time correction has not yet been demonstrated.
Its Waterloo research programme will investigate chip-scale magnetless circulators. A delivered component and measured cryogenic performance remain ahead.
C API compiler passes, circuit serialization and custom operations broaden the SDK. The 2.6.1 patch is already out, so migration checks should include it.
A multi-year agreement with Rhonexum targets the control hardware behind larger trapped-ion systems. Initial delivery is scheduled for the end of 2026.
Quantum Machines describes a September CUDA-Q demonstration linking live qubits, control electronics and GPU computing. Its timing claim measures a specific exchange.
Telefónica and IQM plan an education and research installation at UPM. Delivery and hands-on access are the milestones still to come.
Aalto’s Coherence Quantum spinout has confirmed seed funding. The engineering promise is a less burdensome route between control electronics and cold qubits.
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.
An ETH Zurich spin-off connects quantum software to laboratory signals. Its specifications reveal why the whole feedback loop matters.
