Published Aug 31, 2026• 0 citations

Abstract

Quantum state preservation is a fundamental challenge in quantum information theory, particularly concerning long-distance communication. Current quantum communication protocols, reliant on transmitting qubits, suffer from significant limitations due to signal degradation and decoherence over distances. This paper proposes a novel protocol, termed the 'Quantum Relay' mechanism, that utilizes entanglement as a bridge to preserve the quantum state of a system across vastly extended distances, offering a significant advancement in quantum communication. The core mechanism involves the implementation of a continuous 'quantum relay' that efficiently transfers and aggregates quantum information, mitigating the effects of distance and decoherence. We outline the protocol's architecture, detailing the entanglement generation, relaying, and measurement processes. The theoretical analysis and preliminary implementation demonstrate the potential for maintaining quantum states over considerable distances, paving the way for more robust and scalable quantum communication systems.

Title: Non-Local Quantum State Synchronization – New Framework for Quantum Teleportation

Jincheng Zhang

Quantum teleportation, the process of transferring an unknown quantum state from one location to another without physically moving the particle, has long been considered a cornerstone of quantum information science. However, significant limitations remain, particularly in achieving long-distance teleportation due to decoherence and the challenges of maintaining entanglement over vast distances. This paper introduces a novel framework, termed "Non-Local Quantum State Synchronization" (NLQS), designed to overcome these limitations by explicitly leveraging non-local correlations to establish a shared quantum state. We propose a protocol that utilizes entanglement as a fundamental building block, allowing for the transfer of information across a network, thereby circumventing the constraints imposed by distance and decoherence. The paper details the core mechanisms of the NLQS framework, including the establishment of entanglement, the generation of measurement results, and the subsequent reconstruction of the target state. We present preliminary results demonstrating the effectiveness of the framework in transferring quantum states over a simulated network, highlighting its potential for advancing the field of quantum communication and information processing.
