…le, EUROCRYPT 2026 P-256 qubit cut EUROCRYPT 2026 paper (IACR ePrint 2026/280) 'Reducing the Number of Qubits in Quantum ECDLP' presents prime-curve ECDLP quantum circuits at 3.12n + o(n) qubits vs 5n + o(n) prior (Häner 2020). For P-256: 1,193 logical qubits — a 44% reduction. Bitcoin's secp256k1 shares the same 256-bit curve structure, inheriting the compression directly. This measurably tightens the Babbush et al. <500K physical-qubit ECDLP-256 budget on the same beat the Gidney entry (rank 58) anchors. Techniques: Legendre symbol compression (avoids modular inversion), residue number system lifting, spooky pebbling for space-efficient uncomputation. Sourced from approved quantum signal 5c67cc09 (Apr 26 brief inclusion).

Why
EUROCRYPT 2026 paper — IACR ePrint 2026/280, Reducing the Number of Qubits in Quantum ECDLP — presents prime-curve ECDLP quantum circuits at 3.12n + o(n) qubits versus 5n + o(n) prior (Häner 2020). For P-256: 1,193 logical qubits — a 44% reduction.
Bitcoin's secp256k1 shares the same 256-bit curve structure, inheriting the compression directly. This measurably tightens the Babbush et al. <500K-physical-qubit ECDLP-256 budget that the Gidney / Google Quantum AI entry (PR #25) anchors — the two PRs together close a major coverage gap in the academic ECDLP-research lane.
Techniques: Legendre symbol compression (avoids modular inversion), residue number system lifting to integers, spooky pebbling for space-efficient uncomputation.
