摘要
提出了一种新的量子路由方案,即使两个移动节点不共用EPR纠缠对,仍可实现这两个移动节点之间的量子态无线远程传输。该量子路由方案可以被用来构建量子无线通信网络,同时提出了相应的通信协议。为了实现与现有的经典无线通信网络的融合,方案采用了两层数据库的量子无线通信网络结构。分析表明,在量子信息传输时间和安全性两方面,性能优于量子中继路由方案,具有很高的可扩展性和实用价值。
A quantum routing scheme is proposed to teleport a quantum state from one quantum device to another wirelessly, even though the two devices do not share EPR pairs mutually. The scheme is based on entanglement swapping and quantum teleportation. The model of quantum wireless communication network and eorrelative communication protocol is presented. In order to be compatible with the conventional wireless communication network, the network architecture of a twotier database structure is proposed. In terms of qubit transmission time and security, performance analysis results show thai the proposed scheme is superior to quantum relay routing scheme. The proposed scheme has high scalahility and practicability.
