Quantinuum cuts logical error rate 10x, but bitcoin remains unbroken
- —Logical error rate of 5 per million operations, 100x better than best public rival results
- —Residual logical error falls 12x with each added layer of protection
- —Google previously estimated breaking ECC needs under 500,000 physical qubits
- —About 6.9 million BTC with exposed public keys are theoretically vulnerable
Why it matters: Error-correction gains bring the quantum threat to bitcoin's ECDSA signatures closer, though no real attack exists yet; the market focus is on timelines for post-quantum migration.
