Quantum Echoes Breakthrough Raises Bitcoin Security Concerns
Google’s quantum computing team achieved a 13,000× speed-up on its Willow processor using the Quantum Echoes algorithm to simulate molecular models, marking a practical quantum advantage. This breakthrough advances quantum computing research but does not yet threaten Bitcoin security as current hardware cannot run error-corrected Shor’s algorithm to break 2,048–4,096-bit ECDSA or Schnorr signatures.
Nonetheless, Naoris Protocol’s CEO warns that about 6.65 million BTC in reused addresses could be vulnerable once large-scale quantum computers arrive. Dormant wallets like Satoshi Nakamoto’s may be targeted first. Industry groups and NIST are preparing post-quantum cryptography standards. Traders should adopt new-address practices and monitor quantum-resistant upgrades to safeguard funds ahead of network-wide PQC adoption.
Neutral
In the short term, this breakthrough has minimal direct impact on Bitcoin’s price as current quantum hardware cannot threaten ECDSA security. However, the clear demonstration of a 13,000× quantum advantage reinforces long-term concerns over quantum attacks. Traders may react cautiously, favoring quantum-resistant wallets and monitoring post-quantum cryptography developments. Over the medium to long term, adoption of PQC standards and hybrid signature schemes could require network upgrades, potentially affecting transaction fees and infrastructure investments. Overall, the news is likely to have a neutral effect on BTC price, with more significant implications for security planning than for immediate market movements.
