Temporal-Field Interpretation of Quantum Decoherence

Abstract

Quantum decoherence is conventionally understood as an environment-induced loss of phase coherence, described operationally through reduced density matrices and effective noise models. While this framework successfully captures how decoherence occurs, it leaves open the deeper physical question of why quantum phase coherence is generically fragile and lacks intrinsic protection.

In this work, we propose a reinterpretation of decoherence within the Temporal Theory of the Universe (TTU), where time is treated as a physical field rather than an external parameter. We argue that decoherence can be understood as a manifestation of temporal-field inhomogeneity: a breakdown of global phase synchronization caused by spatial and temporal gradients of the underlying time field. Within this perspective, environmental noise and non-Markovian effects emerge as effective descriptions of deeper temporal misalignment rather than fundamental sources of randomness.

We demonstrate how temporal-field inhomogeneity naturally induces phase damping in the reduced density matrix, leading to decoherence without invoking irreversible information loss. The framework remains fully compatible with standard quantum mechanics at the operational level, while offering a novel physical substrate for coherence, noise, and temporal memory effects. Finally, we outline several experimentally discriminable consequences of this interpretation, positioning it as a falsifiable and conceptually economical extension of existing decoherence theory.
