The implications of quantum nonlocality are briefly reviewed. It is shown that the collapse of the wave function requires the existence of a preferred Lorentz frame. This opens the first door to quantum superluminal communication (QSC). A theory of QSC is deeply analyzed. We demonstrate that the combination of the collapse of the wave function and the consciousness of the observer will permit the observer to distinguish nonorthogonal states under some condition. This provides a principle for realizing QSC. A practical QSC scheme is given based upon the QSC principle. Some evidence of the existence of QSC is also discussed. Besides, a new space-time transformation for QSC is analyzed, and two ways to measure the preferred Lorentz frame are given.
This paper investigates the limitations of quantum entanglement-based long-distance communication protocols primarily due to coherence losses. A novel approach is presented that optimizes entanglement protocols to enhance communication distance and information transmission rates. The core of this method involves designing new entanglement generation and distribution schemes aimed at minimizing coherence degradation and maximizing communication efficiency. Specifically, we introduce a dynamic entanglement allocation strategy coupled with adaptive entanglement purification techniques. The proposed framework addresses the inherent challenges of maintaining entanglement fidelity over extended distances, ultimately aiming to surpass the current distance constraints associated with quantum entanglement communication. The theoretical analysis demonstrates improved performance metrics, including increased communication range and enhanced information transfer rates, relative to existing protocols. This work contributes to a more practical realization of long-distance quantum communication by mitigating coherence losses and offering a pathway towards scalable entanglement-based networks.
