Google Quantum Advance Brings Bitcoin Security Threat Closer, Bitrue Says
Google's Willow quantum breakthrough narrows the timeline for threats to Bitcoin security, though current technology cannot break its cryptography. Magic state cultivation reduced quantum errors 40-fold, achieving 99.99% logical fidelity for T-states. A March 2026 Google Quantum AI white paper estimated breaking Bitcoin's elliptic curve cryptography would require fewer than 500,000 physical qubits. The experiment used at most 54 of Willow's 105 qubits; breaking Bitcoin would require substantially lower error rates.
