论文摘要
连续变量量子密码学在近几十年来迅速发展，但是如何验证连续变量量子系统中的身份仍然是一个紧迫的问题。为了解决这个问题，我们提出了一个基于两种模式挤压真空状态和连续可变传送的相关性的连续变量量子识别（CV-QI）方案。交流的两个参与者之间的双向身份验证可以通过拟议的CV-QI协议来实现。为了保证安全性，我们在提出的CV-QI协议的整个过程中充分利用诱饵状态序列。此外，我们提供了建议的CV-QI协议的安全性分析，并分析表明，保证了建议的CV-QI协议的安全性。
Continuous variable quantum cryptography has developed rapidly in recent decades, but how to verify identity in the continuous variable quantum system is still an urgent issue to be solved. To solve this problem, we propose a continuous variable quantum identification (CV-QI) protocol based on the correlation of two-mode squeezed vacuum state and the continuous variable teleportation. The bidirectional identity verification between two participants of the communication can be achieved by the proposed CV-QI protocol. In order to guarantee the security, we make full use of the decoy state sequences during the whole process of the proposed CV-QI protocol. Besides, we provide the security analyses of the proposed CV-QI protocol, and analyses indicate that the security of the proposed CV-QI protocol is guaranteed.
