Quantum error-correction progress revives debate over Bitcoin's long-term security
- —Google tested 17, 49 and 101 physical qubits, with logical error rates falling as scale grew
- —qLDPC codes aim to cut the number of physical qubits needed per logical qubit
- —A logical qubit held coherence longer than its individual physical qubits for the first time
- —Current quantum systems remain far from breaking Bitcoin's cryptography
Why it matters: Faster progress in error correction would leave Bitcoin and other networks less time to migrate to post-quantum cryptography.
