Bitcoin’s Quantum Migration Playbook — Every Proposal Compared
On March 31, 2026, two research papers dropped on the same day and rewrote everything we thought we knew about Bitcoin’s quantum timeline. Google’s Quantum AI team, alongside researchers from Stanford and the Ethereum Foundation, published findings showing that breaking Bitcoin’s ECDSA encryption could require fewer than 500,000 physical qubits — a roughly 20-fold reduction from prior estimates that hovered in the millions. The same day, a Caltech/Oratomic paper demonstrated that neutral-atom architectures could push that number even […]
