摘　　要：在小型量子网络中采用量子隐形传态通信从物理机制上保证通信信息的绝对安全,但是由于量子信道存在噪声,干扰信息的正确性从而产生误码.为保证通信信息的可靠性,本文提出基于量子纠错码的小型量子网络路由通信协议.根据小型量子网络的路由特点构建路由表;依据路由表实现源量子节点到一跳、两跳目的量子节点的量子隐形传态;利用量子纠错码纠正因噪声产生的误码信息;对该协议的安全性进行理论证明.In small quantum netw ork,the security of communication information can be guaranteed physically by the application of quantum teleportation,the noise of quantum channel w ill be bound to interfere w ith the communication information,leading to the error of code. In order to guarantee the reliability of information communication,a routing protocol of small quantum netw ork is proposed based on quantum error correcting code. According to the routing characteristics of small quantum netw ork,corresponding routing tables are made. On the basis of these routing tables,quantum teleportation can be realized from source quantum node to the nodes w ithin one-hop or tw o-hop. Correct the errors of code resulting from noise of quantum channel based on error correcting code theory,and handle it accordingly,to ensure the reliability of communication information at data link layer. The security of the protocol is proved in theory.
