Theory of Controlled Quantum Decoherence via Force-Field Suppression (CQD-FFS)

This thesis presents a comprehensive theoretical framework for mitigating quantum decoherence in macroscopic systems through selective suppression of environmental interactions, specifically the four fundamental forces. We introduce a dual-phase architecture: the Continuous Event Phase (CEP), where the quantum system is decoupled from gravitational, electromagnetic, weak, and strong nuclear forces to preserve entanglement; and the Utilization Phase (UP), where controlled re-coupling enables information extraction or energy utilization. Inspired by error-corrected quantum computing and dynamical decoupling techniques, the model incorporates force-specific suppression mechanisms based on established physics, with hypothetical extensions for gravity informed by the Diósi-Penrose model. We provide first-principles derivations for the effective interaction Hamiltonian under suppression, focusing on electromagnetic and gravitational forces. A modified Hamiltonian with a suppression operator is derived, and advanced simulations using QuTiP demonstrate enhanced fidelity under suppression, including multi-qubit extensions beyond two qubits and non-Markovian effects. Sensitivity analyses, including Sobol variance-based methods with higher-order interactions and confidence intervals, identify implementation thresholds, and experimental proposals, including those inspired by Geraci's levitated nanoparticle experiments and Tagg's Cheshire Cat tests, outline testable paths in quantum information systems. A thermodynamic analysis ensures compliance with the second law of thermodynamics, extended to non-Markovian regimes. This work bridges quantum mechanics and general relativity, offering innovative insights into gravitational decoherence and potential applications in quantum technologies. All references have been verified for accuracy using current databases (e.g., arXiv, APS Journals), with corrections applied where necessary (e.g., publication years updated to reflect accurate standards, DOIs added).
