Time Field Theory III: Quantum Unification

This paper unifies quantum mechanics with time field theory in flat spacetime. Starting from the linear wave equation of the time field γ, we rigorously derive the Schrödinger equation as the nonrelativistic limit of time field oscillations. Quantum entanglement and the Bell inequality are explained by global phase synchronization of the time field, without hidden variables or superluminal nonlocality. Spin-1/2 particles and photon polarization are consistently described. This work completes the unification of gravity, spacetime geometry, and quantum mechanics within a single, self-consistent, singularity-free framework.
