论文摘要
量子密钥分布(QKD)的理论与实践之间存在很大的差距,因为实际设备不满足安全证明所需的假设。在这里,我们通过基于相干光的传输来介绍一个简单且实用的测量设备(MDI)QKD类型的协议类型来缩小这一差距,为此,我们证明了其在发射机方面的任何可能的设备不完美和/或侧向通道的安全性。除了仅使用一个单个参数使用更简单的实验设置和源表征外,我们还表明该协议的性能与其他MDI-QKD类型的协议类型可比,该协议忽略了几个侧通道的效果。
There is a big gap between theory and practice in quantum key distribution (QKD) because real devices do not satisfy the assumptions required by the security proofs. Here, we close this gap by introducing a simple and practical measurement-device-independent (MDI) QKD type of protocol, based on the transmission of coherent light, for which we prove its security against any possible device imperfection and/or side-channel at the transmitters' side. Besides using a much simpler experimental set-up and source characterization with only one single parameter, we show that the performance of the protocol is comparable to other MDI-QKD type of protocols which disregard the effect of several side-channels.
