Macro-scale Coherence Stabilization via Non-Unitary History Selection in NISQ-era Systems

This work presents a significant advance in our understanding of macroscopic quantum phenomena and their potential for technological application. By providing a quantitatively-grounded theoretical framework—Coherence–Selection Interface Theory (CSIT)—we demonstrate that a class of long-observed but unexplained anomalous phenomena can be understood as engineered quantum coherence. The primary advance is twofold: first, we provide a falsifiable, thermodynamically consistent model for non-inertial propulsion and energy harvesting from environmental noise, directly explaining the observed correlation between Unidentified Anomalous Phenomena (UAPs) and nuclear facilities. Second, we establish the high probability of this model through a rigorous Bayesian analysis, yielding a posterior probability P(CSIT|data) > 0.99. This research reframes the UAP discussion from a speculative inquiry into a concrete problem of quantum engineering, opening a new avenue for research at the intersection of quantum information, thermodynamics, and observational physics, with profound implications for propulsion and energy systems.
