Quantum Temporal Coherence Detection: A Testable Framework for Chronon Field Theory

This paper introduces the Quantum Temporal Coherence Detector (QTCD)—a compact, entangled-qubit-based instrument designed to detect real-time curvature in spacetime as predicted by Chronon Field Theory (CFT). CFT posits that quantum decoherence arises from the geometry of a physically real temporal field Φμ(x)\Phi^\mu(x)Φμ(x), rather than from environmental noise or observer-dependent collapse. The QTCD provides a falsifiable, experimentally implementable framework for testing this claim. The manuscript details the theoretical motivation, device architecture, and measurement protocol of the QTCD. It also presents numerical simulations of wavefunction collapse driven by Chronon field gradients, and explores the broader implications for quantum foundations and quantum computing. In particular, the QTCD offers a novel explanation for unexplained orientation-dependent decoherence in current qubit systems and suggests new routes toward temporally optimized quantum hardware. This work is self-contained and experimentally motivated, while grounded in the geometric framework developed in the companion paper Chronon Field Theory: Unification of Gravity and Gauge Interactions via Temporal Flow Dynamics (Li 2025), also available on Zenodo.
