论文摘要
我们研究了在无线访问混合量子经典网络中使用高维量子密钥分布（HD-QKD）的使用。我们研究访问网络另一端的室内无线用户和中央办公室之间的D维时间相编码状态的分布。我们通过考虑由拉曼散射光对QKD接收器引起的背景噪声的影响来评估在同一信道上传输量子和经典信号的情况下的性能。我们还考虑到室内环境中发生的损失和背景噪声以及分析中的有限关键效果。我们表明，具有D = 4的HD-QKD系统可以胜过基于量子的对应物。
We investigate the use of high-dimensional quantum key distribution (HD-QKD) in wireless access to hybrid quantum classical networks. We study the distribution of d-dimensional time-phase encoded states between an indoor wireless user and the central office on the other end of the access network. We evaluate the performance in the case of transmitting quantum and classical signals over the same channel by accounting for the impact of background noise induced by the Raman-scattered light on the QKD receiver. We also take into account the loss and background noise that occur in indoor environments as well as finite key effects in our analysis. We show that an HD-QKD system with d = 4 can outperform its qubit-based counterpart.
