摘要
量子态远程制备是量子保密通信领域中重要的研究内容之一。本文的主要目的是利用六粒子纠缠态作为量子信道,设计一个两方之间确定性的量子态远程制备协议(DRSP),包括实系数任意三粒子态的远程制备和复系数任意三粒子态的远程制备。其思路可以为后续量子多方保密通信协议的深入研究提供可借鉴的方法。
Quantum state remote preparation is one of the important research contents in the field of quantum secure communication.With a six-particle entangled state being used as a quantum channel,a deterministic quantum state remote preparation protocol(DRSP) between two parties is designed,including remote preparation of arbitrary three-particle states of real coefficients and remote preparation of arbitrary three-particle states of complex coefficients.This idea can provide a reference for further research on the subsequent quantum multi-party secret communication protocol.
