MA Hong-yan · Dianzi xuebao · 2015
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.
