Google reports 40x cut in quantum magic-state errors on Willow chip
Google says its Willow chip cut errors 40x on the scarce "magic states" quantum computers burn through, a step toward smaller, useful machines and toward ones that could threaten today's encryption. A Science result reaches about 99.99% state fidelity, validating a technique already assumed in quantum resource estimates.
