即插即用测量设备无关的量子密钥分发
Plug-and-Play Measurement-Device-Independent Quantum Key Distribution
摘要：
量子密钥分发（QKD）是基于量子物理定律的无条件通信安全保证。然而，实际的QKD由于设备缺陷而遭受许多量子黑客攻击。从安全性的角度来看，与测量设备无关的量子密钥分发（MDI-QKD）由于消除了所有可能的检测漏洞而备受关注。然而，由于用于来自远程方的光子之间的模式匹配的主动控制单元，MDI-QKD的实现是非常不切实际的。在这篇文章中，我们提出了一种新的方法，其中的不稳定性问题得到解决，没有任何主动控制单元。通过在MDI-QKD中引入即插即用（P&P）的概念，自然可以保证光子之间的不可分割性。我们用原理验证实验证明了P&P MDI-QKD的可行性。
英文摘要：
Quantum key distribution (QKD) gaurantees unconditional communication security based on the laws of quantum physics. However, practical QKD suffers from a number of quantum hackings due to the device imperfections. From the security standpoint, measurement-device-independent quantum key distribution (MDI-QKD) is in the limelight since it eliminates all the possible loopholes in detection. Due to active control units for mode matching between the photons from remote parties, however, the implementation of MDI-QKD is highly impractical. In this article, we propose a novel method in which the indistinguishability issue is resolved without any active control unit. By introducing Plug-and-Play (P&P) concept into MDI-QKD, the indistinguishability between photons can naturally be guaranteed. We show the feasibility of P&P MDI-QKD with a proof-of-principle experiment.
