Google Willow Chip Cuts Quantum Errors 40-Fold

Google announced its Willow quantum chip reduces preparation errors about 40-fold by using a cultivation method to produce magic states. The experiment achieved 99.99 percent fidelity for passing states, though only 8 percent of attempts succeeded. Researchers say this advances engineering needed to sustain roughly 500,000 reliable states per second required for modeled attacks on Bitcoin wallets.
