Quantum Researchers Say 30K Qubits Could Crack Bitcoin Keys in Just One Hour

New research from quantum computing company Alice & Bob suggests that breaking the cryptography protecting the Bitcoin network could require far fewer quantum computing resources than previously believed, adding urgency to efforts to prepare the cryptocurrency for a post-quantum future. The Paris- and Boston-based company announced Thursday that its researchers estimate a fault-tolerant quantum computer equipped with approximately 29,588 physical qubits could solve a 256-bit elliptic-curve cryptography problem in just 61.8 minutes. The mathematical problem underpins the digital signatures used to authorize bitcoin transactions.
