【摘要】：量子信号和经典光信号共纤同传技术是光纤量子保密通信实用化进程中的关键技术,该技术可以显著降低量子保密通信网络的建设成本。通过比较离散变量量子信号和连续变量量子信号分别与经典光信号共纤同传的基本原理,提出了基于少模光纤(FMF)模分复用(MDM)的离散变量量子信号、连续变量量子信号以及经典光信号三者共纤同传的方法,降低了非线性损伤及噪声,有效地利用了现有的光纤资源。结合离散变量量子密钥分发技术和连续变量量子密钥分发技术的优势,构建了更加稳定有效的量子保密通信网络。
[Abstract]:The common fiber co-transmission technology of quantum signal and classical optical signal is the key technology in the practical process of quantum secure communication, which can significantly reduce the construction cost of quantum secure communication network. By comparing the principle of discrete variable quantum signal and continuous variable quantum signal co-propagating with classical optical signal, a discrete variable quantum signal based on less mode optical fiber (FMF) mode division multiplexing (MDM) is proposed. The method of co-propagation of continuous variable quantum signal and classical optical signal reduces the nonlinear damage and noise and effectively utilizes the existing optical fiber resources. Combining the advantages of discrete variable quantum key distribution and continuous variable quantum key distribution, a more stable and effective quantum secure communication network is constructed.
