中文摘要：
量子信令态在传输过程中，由于环境影响产生退相干，造成信令损伤，从而会对构建高生存性的量子纠缠信令网产生影响. 为分析所造成的影响，建立了自然灾害下的量子信令网Poisson损伤模型. 首先，根据信令保真度定义了灾害级数；其次，提出信令态平均损伤量子比特数，并给出信令网生存函数；最后，研究了信令损伤的修复策略并进行仿真. 仿真结果表明，灾害级数的增加会大大降低信令网生存性，而增加信令转接点数和控制信令损伤上限可改善生存性，且该修复策略循环次数少，并可将信令态的保真度由0.6快速提高到0.9，信令网的生存函数由0.4提高到0.9.
英文摘要：
Quantum signaling states have decoherence because of the environment during the transmission. It causes signaling damage and thus will have impact on building high survivability quantum entanglement signaling network. In order to study the influence deeply, Poisson damage model of quantum signaling network is established. First, disaster magnitude is defined base on signaling fidelity. Second, average damage signaling quantum bits and survival function of quantum signaling network is put forward by basic quantum theory. At last, research on the signaling damage repair strategy and simulation is analyzed. Simulation results show that increasing of disaster magnitude will greatly reduce the signaling network survivability. However, increasing the nodes and controlling signaling damage caps may improve survivability. The repair strategy which costs small number of cycles can rapidly increase the signaling fidelity from 0.6 to 0.9 and the survival function of the signaling network from 0.4 to 0.9.
