Google announced that its Willow quantum chip has reduced the error rate by approximately 40 times when preparing the special states required for quantum computing, thereby alleviating one of the hardware bottlenecks for cracking Bitcoin wallets in the future. This breakthrough addresses a costly step in quantum computing: how to efficiently prepare "magic states" for computation. Google previously estimated that a future superconducting quantum computer with fewer than 500,000 physical qubits could theoretically crack Bitcoin and Ethereum wallet encryption under specific hardware assumptions.
