Precise theorem

Theorem 1 (eqs 23-25, Methods p.~17): eps_unf = sum_{l=0}^{floor(N(1-nu_unf))} C(N,l)(1-Pnoqub,theta)^l Pnoqub,theta^{N-l} + sum_{l=0}^{floor(n gamma_err)} C(n-floor(N nu_unf), l)(1-Pbound)^l Pbound^{n-floor(N nu_unf)-l}, under max 2 P_MC(chi) <= Pbound < 1 etc. Reported 5.52e-9-unforgeable, 2.1e-11-correct after 7-sigma parameter-confidence correction (eqs 26-29).

Versionversion: arXiv v2 PDF read. No journal reference on arXiv page as of 2026-10-11 (journal publication NOT_FOUND).
Correction statuscorrection_status: n/a (preprint); no erratum found.
Input modelinput_model: Heralded single-photon source (88.24% heralding efficiency); Alice does not report losses (gamma_det=1, n=N); preparation angle theta=5.115515 deg with P_theta=0.027.
Verifier modelverifier_model: Two presentation regions; local FPGA validation at 10 Gbps; intra-city 2.77 km and inter-city 60.54 km links.
Adversary capabilitiesadversary_capabilities: Dishonest Alice arbitrary quantum operations (maximum-confidence measurement bound per pulse); privacy assumes no side channels.
Tested parameterstested_parameters: N=10,048; E=0.062550; Pnoqub=4.9e-5; beta_PB=0.001360; beta_PS=0.001120 (7-sigma); gamma_err=0.094; nu_cor=0.457643134; Pnoqub,theta=0.027047677; Pbound=0.884130 (Mathematica); nu_unf=0.037547677; eps_unf=5.49112e-9 -> eps'_unf=5.52e-9; transaction time 304.20 us, comparative advantage 39.80 us.
Proof dependenciesproof_dependencies: Maximum confidence measurements (ref 29); Lemmas 2-3 improved Chernoff bounds vs P03; SI proofs.
Datasetsdatasets: Not identified (NOT_VERIFIED).
Codecode: Not identified (NOT_VERIFIED).
Licenselicense: arXiv CC BY 4.0 (paper text).
Limitationslimitations: Preprint, not peer-review confirmed; side-channel countermeasures not implemented; QMint recomputation of eq.(28)-(29) gives 5.507e-9 and eq.(27) gives 1.82e-11 vs reported 5.52e-9 / 2.1e-11 (reported values are larger, i.e. conservative; flagged, not an erratum).
What QMint addswhat_QMint_adds: This is PRIOR ART for (i) a measured S-token transaction-time advantage and (ii) propagating 7-sigma device-parameter confidence into an unforgeability epsilon. QMint must not claim either. QMint could only add systematic multi-parameter optimisation and independent re-checking.
