摘要:

提出了一种基于单光子偏振和空间模式自由度的量子对话协议。在所提出的量子点协议中,用于编码的偏振和空间模式自由度中的单光子的初始状态在两个通信者之间通过从一个通信者到另一个通信者的辅助对应物的直接传输而私有地共享。结果,避免了信息泄漏问题。此外,详细的安全性分析还表明,所提出的QD协议能够抵抗Eve提出的几种著名的主动攻击,如特洛伊木马攻击、拦截重发攻击、测量重发攻击和纠缠测量攻击。该量子点协议只需要偏振和空间模两个自由度的单光子作为量子源,并采用单光子测量。因此,它是可行的,在实践中的制备和测量的一个单一的光子在偏振和空间模式的自由度可以完成与目前的实验技术。

英文摘要:

In this paper, a novel quantum dialogue (QD) protocol is proposed based on single photons in both polarization and spatial-mode degrees of freedom. In the proposed QD protocol, the initial states of single photons in both polarization and spatial-mode degrees of freedom used for encoding are privately shared between two communicants through the direct transmissions of their auxiliary counterparts from one communicant to another. As a result, the information leakage problem is avoided. Moreover, the detailed security analysis also shows that the proposed QD protocol can resist Eve's several famous active attacks, such as the Trojan horse attack, the intercept-resend attack, the measure-resend attack and the entangle-measure attack. The proposed QD protocol only needs single photons in both polarization and spatial-mode degrees of freedom as quantum resource and adopts single-photon measurements. As a result, it is feasible in practice as the preparation and the measurement of a single photon in both polarization and spatial-mode degrees of freedom can be accomplished with current experimental techniques.
