aiqbench analysis

This paper presents a rigorous geometric framework linking Berry phases, entanglement, and coherence to optimize CHSH correlations in noisy quantum systems. By analyzing how recorded phase noise affects deterministic quantum channels, the study establishes specific reliability laws for resource intervals without claiming universal bounds on entanglement lifetimes. The work advances fundamental understanding of quantum nonlocality and error certification relevant to transport and thermal applications.

A Multi Affine Geometric Framework for Quantum Nonlocality. Unifying Berry Phases, Entanglement, and Coherence

arXiv2 min read

arXiv:2503.17995v2 Announce Type: replace Abstract: We relate Berry-phase control and retained entropy geometry to recoverable coherence, entanglement, and Clauser-Horne-Shimony-Holt (CHSH) correlations. For a depolarized Bell pair subject to recorded phase noise, we determine exact CHSH optima when Bob retains his record and when he compresses it with his qubit into one qubit by any deterministic quantum channel. Some records preserve a violation that every such compression loses. The retained transverse metric gives sharp resource intervals. Nevertheless, for every finite derivative order, two finite readouts of the same noise can match all pulled-back monotone-metric and relative-entropy derivatives at faithful diagonal inputs while giving opposite recovered CHSH outcomes. Complete transverse entropy response determines the reliability law. A finite transitionless Berry loop realizes the channel; zero-expectation conditional control errors give a quadratic reduced-channel accuracy certificate. Transport, thermal, and accelerated-detector applications specialize established channel criteria under explicit preparation and accuracy assumptions. These model-dependent certificates supply neither a universal entanglement lifetime nor a detector-independent acceleration bound.
