摘要/Abstract

摘要：研究了三纠缠粒子量子隐形传态网络的物理基础，得到了基于三粒子GHZ态下隐形传态的幺正变换矩阵，设计了一个基于三纠缠粒子的令牌环量子隐形传态网络，给出了一个基于该网络的通信方案.笔者设计的网络中的各站点可实现任意站点间的量子通信，其监控站还可对整个网络的通信情况进行监控和计费管理.

关键词： 量子通信, 量子隐形传态, GHZ态, 令牌环网

Abstract: The authors investigate physical principium for building the quantum teleportation net by using three-particle GHZ states，find out unitary transformation matrix for quantum teleportation of three-particle GHZ states,and design a token ring-shaped quantum teleportation net.The authors propose a scheme for quantum communications net and its protocol.If all stations work as the scheme,quantum communications between any two stations may be realized.All station and manage expense can be monitored by using monitor station.

Key words: quantum communications, quantum teleportation, GHZ states, token ring-shaped net
