| 摘 要： | 为了解决EPR纠缠通过大气空间在通信终端之间的分发问题,使量子移动用户之间及时建立纠缠,提出了一种新的陆地量子移动通信网络的量子纠缠多址中继方案和分区服务模型.分析比较了基于量子受控非门和极化分束器的两种纠缠纯化方法.结果表明:即使在量子移动终端之间没有共享EPR纠缠对的情况下,通过纠缠纯化和量子多址中继,仍然可以完成量子态的无线传输,并且其传输时延与所经过的链路距离和基站数目无关|因此,从数据传输时延的观点来看,该方案是最优的.本研究对于构建大规模量子移动通信网具有一定的奠基作用.

| Abstract: | A novel service model of land quantum mobile communication systems and the scheme of quantum multiplexing relay were proposed.The two quantum entanglement purification method,one is based on the quantum controlled-not gate,the other is based on polarizing beam splitter,were compared then.Theoretical analysis results show that the proposed scheme can transmit quanta states with no EPR pairs shared by source and objective nodes,and the time delay in transmission has nothing to do with the number of wireless hopping and the distance of link. |
