Google Touts ‘Magic’ Quantum Breakthrough as Bitcoin Q-Day Threat Looms
Key Highlights: Google has developed a novel quantum computing technique to resolve processing bottlenecks by filtering out noise and transferring purified quantum states between error-correction architectures. Earlier research suggests that breaking Bitcoin’s elliptic-curve digital signatures could require fewer than 500,000 physical qubits, potentially exposing roughly 6.9 million BTC linked to revealed public keys. Major industry ...
