论文摘要
在本文中，提出了一种新型的信息泄漏量子对话（QD）方案，该方案在极化和空间模式的自由度中均提出了单个光子，该协议均提出了使用量子加密技术来克服信息泄漏问题。在拟议的QD协议中，在传输过程中，用于编码两个私人经典列的极化和空间模式的自由度的单个光子都受量子加密技术和诱饵光子技术的保护。为了避免信息泄漏问题，用于编码两个交流者的私人经典位的自由度和空间模式的自由度中的单个光子的初始状态通过量子密钥加密和解密在两个交流者之间共享。提出的QD协议的信息理论效率高达40％。
In this paper, a novel information leakage resistant quantum dialogue (QD) protocol with single photons in both polarization and spatial-mode degrees of freedom is proposed, which utilizes quantum encryption technology to overcome the information leakage problem. In the proposed QD protocol, during the transmission process, the single photons in both polarization and spatial-mode degrees of freedom used for encoding two communicants' private classical bits are protected by both quantum encryption technology and decoy photon technology. For avoiding the information leakage problem, the initial states of the single photons in both polarization and spatial-mode degrees of freedom used for encoding two communicants' private classical bits are shared between two communicants through quantum key encryption and decryption. The information-theoretical efficiency of the proposed QD protocol is as high as 40%.
