FieldHash: Quantum Physical Unclonable Functions for Tamper-Evident Digital Provenance

FieldHash is a quantum-anchored provenance system for tamper-evident digital records. This Zenodo record is the canonical standalone technical archive for the preprint, evidence, and reproducibility materials. What this archive includes Preprint and technical brief Hardware evidence from IBM Torino and Quantum Inspire Red-team and adaptive adversarial evaluation artifacts Cost-scaling and economic-viability addendum Reproducibility package with manifest, job index, and support tools Key evidence highlights Standard-profile uniform-blend attack: 15/800 accepted (1.875%, 95% CI [1.14%, 3.07%]) Hardened profile on the same model: 0/800 accepted Production-gated verification (policy + integrity signature binding, no-signing-key assumption): 0/5000 accepted per tested adaptive model (Wilson 95% upper bound 0.0768%) Claim boundary This work does not claim asymptotic runtime speedup. It demonstrates a security-oriented quantum utility: physics-based tamper evidence and offline verification continuity.
