摘要: 针对基于纠缠态的量子通信网络，提出了网络模型。基于网络模型，首先分析了基础链路的量子信道建立速率。然后根据基础链路的量子信道建立速率，针对不同的量子信道建立方法，对中继长链路上的量子信道建立速率进行分析，得到在逐点方法和分段方法下所对应的量子信道建立速率。最后，利用逾渗模型，对大规模纠缠态量子通信网络中任意两点间的量子信道建立速率进行分析，推导出n个节点量子通信网络中，量子信道建立速率为?(1/n)。Abstract: Targeting the quantum communication network based on entangled states, a network model is proposed. According to the model, the quantum channel establishing rate of basic links is then analyzed. For different quantum channel establishment methods, the quantum channel establishing rates of long relay links are also analyzed. Then the quan-tum channel establishing rates corresponding to the point-by-point method and segmentation method are calculated. Finally, the quantum channel establishing rate between two arbitrary points in a large-scale quantum entanglement com-munication network is analyzed based on the percolation model. The quantum channel establishing rate in a quantum communication network of n nodes is?(1/n).
