本文根据量子密钥分发协议的特点,对近期分别由M. Lucamarini等和马雄峰等提出的两类量子密钥分发协议,即双场量子密钥分发协议(TF-QKD)、相位匹配量子密钥分发协议(PM-QKD)与H.K等提出的测量设备无关的量子密钥分发协议(MDI-QKD)进行多方分析,确定比较基准和分类属性,在同一层次上横向比较了这三种协议在设备实现、诱骗态方法、光子源、干涉测量类型、密钥率、安全性证明等方面的特性,结果表明相位编码能有效提高光脉冲传输稳定性,结合单光子干涉以及相位后补偿方法能够进一步提高密钥生成率。

Based on the characteristics of the quantum key distribution protocol,this paper analyzes two types of quantum key distribution protocols proposed by M. Lucamarini and Ma Xiongfeng recently,namely Twin-Field Quantum Key Distribution,Phase-Matching Quantum Key Distribution and Measurement Device Independent Quantum Key Distribution proposed by H.K,then determines the baselines and classification properties to compare the device implementation,decoy state method,photon source,interferometry type,key rate and security proof of these three protocols,which shows that phase encoding can improve the stability of optical pulse transmission effectively.Moreover,single photon interference and phase postcompensation can further improve the key generation rate.
