…tional secp256k1 ECDLP paper arXiv 2603.28846 (Babbush, Gidney et al., Mar 2026 + v2 Apr 15): the foundational Google Quantum AI paper that compressed the secp256k1 ECDLP threshold to under 500K physical qubits and a ~9 minute crack window. v2 distinguishes fast-clock (superconducting/ photonic) vs slow-clock (ion-trap/neutral-atom) architectures, quantifying on-spend mempool attack feasibility. Gidney's separately published 10% CRQC-by-2030 estimate is the explicit anchor cited in Neha Narula's score-update post (already on map at rank 43). Babbush threshold figures (1,200 logical qubits / <90M Toffoli gates) are now the de facto reference standard across bitcoin-dev PQ threads, BIP-360/BIP-361 drafts, and Bitcoin Optech newsletters. Sourced from approved quantum signals 601f4512, 5c67cc09, da64a51c (3 brief inclusions Apr 26).
