Google Achieves 99.99% Accuracy in Quantum 'Magic State' Breakthrough
- —Magic state accuracy reached 99.99%, with an error rate of 1 in 10,000
- —Errors reduced 40-fold versus uncultivated states
- —Breaking ECC would require scaling the architecture 100,000x
- —Cracking Bitcoin would need 1,200–1,450 logical qubits versus the current 105
Why it matters: The quantum milestone intensifies debate over post-quantum blockchain security, though the near-term threat to Bitcoin and Ethereum remains distant.
