论文摘要
在水下通道中经历的吸收，散射和湍流严重限制了量子通信的范围。在本文中，为了克服范围限制，我们研究了一个多跳下水下量子键分布（QKD），其中中间节点有助于源节点和目标节点之间的密钥分布。我们考虑部署被动延迟，这些弹奏只需将Qubits重定向到下一个继电器节点或接收器，而无需进行任何测量。基于近场分析，我们在不同大气条件下介绍了透明海洋中继电器辅助QKD方案的性能。我们进一步研究了系统参数（孔径大小和检测器视野）对可实现距离的影响。
Absorption, scattering, and turbulence experienced in underwater channels severely limit the range of quantum communications. In this paper, to overcome range limitations, we investigate a multi-hop underwater quantum key distribution (QKD) where intermediate nodes help the key distribution between the source and destination nodes. We consider deployment of passive-relays which simply redirect the qubits to the next relay node or receiver without any measurement. Based on near-field analysis, we present the performance of relay-assisted QKD scheme in clear ocean under different atmospheric conditions. We further investigate the effect of system parameters (aperture size and detector field-of-view) on the achievable distance.
