摘要/Abstract

摘要： 2012 年提出的测量设备无关量子秘钥分发( MDI-QKD) 协议,将所有测量端安全漏洞同时关闭。MDI-QKD 及其之前的QKD 协议的成码率和信道传输效率均呈线性关系,都存在PLOB 界。2018 年提出的双场量子密钥分发(TF-QKD)协议不仅具有测量设备无关特性,还可突破PLOB 界,将成码效率提高到与信道传输效率的平方根相关。通过梳理MDI-QKD、TF-QKD 协议及其各种变种协议的理论和实验进展,简要总结其特点,并对其未来发展进行了展望。

Abstract: The measurement equipment-independent protocol MDI-QKD, which was proposed in 2012, closes all security vulnerabilities at the measurement end at the same time. The code rate and channel transmission efficiency of MDI-QKD and its previous QKD protocols are in a linear relationship, and both have a PLOB upper limit. The twofield quantum key distribution protocol proposed in 2018 not only has the characteristics of measurement equipment independence, but also breaks the upper limit of PLOB and improves the coding efficiency to the square root of the channel transmission efficiency. Through combing the theoretical and experimental progress of the MDI-QKD, TFQKD protocol and various variants of the protocol, the characteristics are briefly summarized, and the future development is prospected.

Key words: security of QKD, MDI-QKD, TF-QKD
