The result is a faster, high-fidelity single-qubit or two-qubit gate on superconducting hardware, a metric that matters because gate speed and error rates jointly set how many operations fit before decoherence. Readers should check which gate type was measured and whether 99.98% fidelity held under realistic conditions, since benchmark gates often differ from those used in full error-corrected algorithms. The paper in Nature Communications will be the place to verify the claim.

Scientists from the Jülich Research Centre in Germany and other institutions have carried out a quantum operation on superconducting qubits that took just 6.8 nanoseconds, with an accuracy exceeding 99.98%. On superconducting quantum computers, such operations typically take several tens of nanoseconds. The work shows that extremely short quantum gate operation times and high operational accuracy can be achieved at the same time, setting a new benchmark for quantum gates and providing an important reference for further optimizing quantum systems. The related paper was published in the latest issue of Nature Communications. (Science and Technology Daily)
