Temporal Information Dynamics in the Scalar Temporal Field Ontology: Part VII — Quantum Information Dynamics, Decoherence, and Entanglement Flow

Part VII of the Temporal Information Dynamics (TID) series develops the full quantum-information layer of the Scalar Temporal Field Ontology (STFO), where time is a physical scalar field τ(x) and information evolves along its integral curves. This work extends Parts I–VI by deriving the complete quantum dynamics implied by τ-geometry: the τ-modified Schrödinger equation governing intrinsic temporal evolution, the temporal decoherence kernel generated by fluctuations δτ, a covariant τ-Lindblad master equation for open quantum systems, directional entanglement flow induced by ∇μτ, τ-dependent deformations of the quantum Fisher metric, modified quantum-channel capacities, coherence lengths, and error exponents, τ-corrected propagators, Green’s functions, and canonical commutators, and a fully geometric τ-weighted path-integral formulation. Across all levels—Hamiltonian, thermodynamic, geometric, and quantum—information flow becomes a direct probe of τ-gradients and temporal curvature. The resulting framework is testable in atom interferometry, optical and microwave clock networks, spin-echo experiments, and quantum computing hardware. This paper completes the quantum-information pillar of STFO and unifies classical information flow, thermodynamic irreversibility, geometric curvature, and quantum coherence into one continuous, falsifiable theory of temporal dynamics.
