Causal Entanglement Decoherence (CED) - A Quantum Gravity-Induced Mechanism for Entanglement Loss in Curved Spacetime

We propose the Collective Entanglement Disruption (CED) hypothesis, which describes how spacetime curvature, quantum vacuum fluctuations, and gravitationaltime dilation collectively contribute to quantum decoherence. This paper derives a gravitational decoherence rate from QFT in curved spacetime and integrates it into an entanglement entropy evolution equation. The Collective Entanglement Disruption (CED) framework introduces a novel mechanism for entanglement loss in curved spacetime, integrating quantum gravity effectsinto entanglement evolution.Our key result is that gravitational time dilation explicitly modulates entanglement decoherence, leading to unique testable predictions.
