摘要
在量子通信过程中,通信质量主要受到量子噪声、通信节点数、纠缠粒子数等因素影响,为得到更适合实际应用的通信路由,对相位阻尼信道进行研究。在以最小等效阻尼系数为度量的最佳中继路由算法基础上进行改进,给出一种综合性路由度量的最佳路由选择方案。该方案充分考虑了对通信路由影响较大的几个因子,并采用路径先验方案以避免路径失效后网络进行通信请求。理论分析与仿真对比结果表明,该路由协议使路径节点中的最小纠缠粒子对数得到明显提高,从而提高了网络稳定性。
In the process of quantum communication,the communication quality is mainly affected by quantum noise,the number of communication nodes and entangled particles,etc.In order to get the communication routing which is more suitable for practical com⁃munication application,the phase-damped channel is studied.In order to improve the optimal relay routing algorithm based on mini⁃mum equivalent damping coefficient,an optimal routing scheme based on comprehensive routing metrics is presented.This scheme ful⁃ly considers several factors which have great influence on communication routing and adopts a path prior scheme to avoid communica⁃tion requests after path failure.Theoretical analysis and simulation comparison show that the minimum entangled particle logarithm in the path node is significantly improved by the routing protocol,which thereby improves the stability of the network.
