摘要
为有效解决量子网络的安全问题,提出了多跳环形量子网络的量子密钥共享协议。该协议在由2N+1个量子节点组成的环形网络中通过EPR对传输密钥。量子节点t0利用CONT门、H门操作,将密钥通过t1传递给t2,再多跳的依次传递给量子节点t4,…,t2N通过t3,…,t2N-1,最终将共享信息传递给最后的量子节点。该协议利用现有的手段可以实现。
To deal with secret for ring quantum network, a mutual quantum secure direct communication scheme which shared the EPR state in the multihop ring quantum networks is presented. The communication is based on Einstein-Podolsky-Rosen pairs （EPR pairs） and teleportation between the quantum nodes. After insuring the security ofthe quantum channel through controlled-NOT （CONT）gate operations and Hadamard （H） gate operations on them. The sequence sent to t2 from to through t1, then multihop transmits them to t4, ..., t2N supervised via t3, ..., t2N-1. This scheme is feasible with present-day techniques.
