摘　　要：为了解决量子信令的最佳帧长问题,本文提出了一种基于保真度的量子信令最佳帧长的算法.根据量子信令收发模型,定义了一个由若干量子态组成的量子信令的联合保真度,并通过计算链路的有效利用率而得出最佳帧长的算法.仿真结果与理论分析完全相符,从而表明本文提出的最佳帧长算法稳定、易行,可以应用到复杂多变的实际环境中.In order to solve the problem of quantum signaling optimal frame size,a quantum signaling optimal frame size algorithm based on the fidelity was proposed.Firstly,a basic quantum signaling transceiver model was analyzed.Then,a joint fidelity of quantum signaling which consists of several quantum states was defined.Finally,the optimal frame size algorithm was given by calculating the link effective utilization.Simulation result is consistent with the theory,which proves that the proposed algorithm is feasible and simple and can be applied to complicated practical environments.
