Bitcoin Quantum Attack Just Got Cheaper, and Researchers Are Paying Attention

A potential Bitcoin quantum attack just became a little less expensive on paper. Researchers have reduced the estimated resources needed for a key operation involved in breaking the cryptography protecting Bitcoin and Ethereum, cutting the benchmark dramatically over the course of a two-month challenge.The final published circuit requires 1,151 logical qubits and 1.30 million Toffoli gates, according to a technical paper led by Theta Labs CTO Jieyi Long and researchers connected to several crypt
