Researchers at quantum computing firm Alice & Bob estimate that a machine with about 29,588 physical qubits could break the cryptography protecting bitcoin wallets in roughly 62 minutes. That figure is about 17 times lower than Google's March estimate of fewer than 500,000 qubits, though the studies use different hardware designs and assumptions. The findings remain theoretical. The attack would be too slow to reliably intercept transactions before confirmation, but more than six million bitcoins sit at addresses with exposed public keys, giving attackers more time. The researchers urge Bitcoin developers to adopt quantum-resistant security now, warning upgrades could take years as threatening hardware approaches the early 2030s.
