Google cuts quantum errors 40-fold: Is Bitcoin at risk?

Google has demonstrated a 40-fold reduction in quantum computing errors using its Willow processor, advancing a technology that researchers believe could eventually challenge the cryptography protecting Bitcoin. Google reduced quantum computing errors approximately 40-fold using magic state cultivation on its Willow processor. Google's researchers achieved 99.99% logical fidelity while testing purified quantum states on real computing hardware. Glassnode estimated 6.04 million BTC had exposed public keys, representing 30.2% of mined Bitcoin. Google's earlier research estimated future cryptographic attacks could require fewer than 500,000 physical quantum qubits.
