论文摘要
我们使用[phys.rev.lett。〜127，〜110505，〜2021]中报道的高维量子密钥分布协议对高维量子密钥分布协议的实际实施。在这里，我们通过模拟不同类型的通道噪声对无噪声实验数据的影响来完善那里进行的噪声鲁棒性分析。此外，我们将分析扩展到两种不对称场景。在第一种情况下，纠缠源被放置在爱丽丝实验室中，因此只能考虑一个嘈杂的渠道。在第二种情况下，鲍勃的探测器被放置在不同的物理位置，因此这种情况实现了一个简单的通信网络。我们的分析也可以扩展到其他实验平台，因此为高维量子密钥分布协议的公平噪声鲁棒性比较提供了一个新颖的框架。
We revisit the practical implementation of high-dimensional quantum key distribution protocol using path entanglement reported in [Phys.Rev.Lett.~127,~110505,~2021]. Here we refine the noise robustness analysis performed there by simulating the effect of different types of channel noise on the noiseless experimental data. Further, we extend the analysis to two kinds of asymmetric scenarios. In the first scenario the entanglement source is placed in Alice's lab and thus Only one noisy channel has to be considered. In the second scenario, Bob's detectors are placed at different physical locations and therefore such scenario implements a simple communication network. Our analysis can also be extended to other experimental platforms and therefore provides a novel framework for fair noise robustness comparison of high-dimensional quantum key distribution protocols.
