The research shows quantum computers may break bitcoin and ether wallet encryption with far fewer qubits than previously thought, accelerating the push toward post-quantum security. A research paper from Caltech and quantum startup Oratomic found that the cryptography protecting bitcoin and ether wallets could be broken with as few as 10,000 physical qubits, far below earlier estimates of hundreds of thousands. Using Google's quantum circuits as a baseline, the authors say a neutral-atom q…
