论文摘要
我们检查了在子载波波量键分布(SCW QKD)系统中实现相干检测的不同方法。对于经典的波场,我们介绍了描述同型类型和杂型型相干检测方案的模型,以从SCW QKD中使用的正交相位编码的多模信号中提取信息。实验证实了所提出的方案的实际可行性。
We examine different methods to implement coherent detection in the subcarrier wave quantum key distribution (SCW QKD) systems. For classical wavefields, we present the models describing homodyne-type and heterodyne-type coherent detection schemes needed to extract information from the quadrature phase-coded multimode signals used in SCW QKD. Practical feasibility of the proposed schemes is corroborated by the experiments.
