【摘要】 分析了未知的三个三态粒子纠缠态的隐形传送过程,结合纠缠源的特性,提出了量子信道时分复用方案.同时还提出了一种可传送多粒子纠缠态的量子时分多路通信方案和量子多用户协议.研究结果表明,该方案与采用BB84协议的量子通信系统相比,不仅能够实现量子多用户安全保密通信,而且误码率低.更多还原

【Abstract】 The teleportation of three entangled states of three-state particles is analyzed.Aquantumchannel time multiplex scheme based on characteristics of entangled source is proposed.The quantum time division multiplexcommunication scheme capable of transmitting multi-particles entangled state is presented finally.The results show that the scheme above not only has a lower BER than BB84 protocol but can realize the multi-users secret communication.更多还原
