Original Note:
Incorrect. Bitcoin relies on 2 kinds of encryption: ECDSA256: cracking require over 1m qubits. Willow’s 105 isn’t close. SHA256: requires a different approach (Grover’s algorithm) and millions of physical qubits to pose a threat. https://blog.google/technology/research/google-willow-quantum-chip/ https://cointelegraph.com/news/google-unveils-new-quantum-computing-chip-clock-ticking-crypto-encryption https://u.today/googles-new-quantum-chip-wont-kill-bitcoin-expert-says?amp
