摘　　要：本文提出了一种新的网络纠缠桥接方案,利用量子纠缠交换技术,在任意贝尔态的基础上实现量子链路的构建,通过定义一组系数矩阵,使目的节点可直接获得所需的恢复操作,更方便地实现初始态的重建,并对更为一般的n跳通信情况进行了研究,解决了远距离的量子信息传输的问题。A novel bridge scheme of Quantum Wireless Wide-Area Network was proposed. In the scheme, entanglement swapping and arbitrary Bell state were utilized for establishing quantum route between the source node and the destination node. By defining coefficient matrix, the destination node can directly obtain the recovering algorithm through simple matrix calculation. In addition, a more general case of n-hop case has been generalized and the problem of quantum information transmission over long distances has been solved.
