Can Quantum Computers Break Crypto in Minutes? Inside Google’s New Findings

Google has accelerated its post‑quantum migration deadline to 2029 after two new papers showed that Shor’s algorithm can crack secp256k1 signatures with roughly 1,000 logical qubits or about 10,000 physical qubits, dramatically shrinking the resources needed to threaten Bitcoin, Ethereum and other cryptographic systems.
