    Oxford Achieves 10⁻⁷-Level Qubit Gate Error, Shattering Quantum Fidelity Records

    Physicists at the University of Oxford have set a new world record for quantum logic accuracy, achieving single-qubit gate error rates below 10^-7 – meaning fidelities exceeding 99.99999%. The breakthrough, reported in a study published in Physical Review Letters in June 2025 marks the lowest error ever recorded for any ... Read More

    A Reality Check on Forbes’ “20 Real-World Quantum Computing Applications”

    A few of Forbes’s examples are genuinely promising; several smash together disparate ideas without noting the engineering road‑map; and some miss key caveats that separate “demo‑ready” from “production‑ready.” The authors could have done a sharper job sorting mature use cases (think quantum key distribution) from long shots (say, universal quantum ...
