Quantum Threat to Bitcoin Accelerates
A joint paper from Google's quantum team, the Ethereum Foundation, and Stanford's Dan Boneh demonstrated ECDSA key recovery in roughly 9 minutes using 1.2k-1.4k logical qubits, a 10x reduction from prior estimates of ~10k, while Oratomic founder Dolev Bluvstein's neutral atom research cut physical qubit requirements from 100k+ to 19k, with Caltech already operating a 6,100-qubit neutral atom array. Google moved its internal post-quantum cryptography deadline to 2029, ahead of NIST's 2030-2035 guidance. The use of a zk proof for responsible disclosure rather than publishing the quantum circuit establishes a precedent for increasing opacity among quantum labs.
