【摘要】：提出了一个利用五粒子团簇态实现的可控量子安全直接通信方案.在这一方案中,首先信息发送者Alice、信息接收者Bob和控制者Charlie共享由Alice制备的一有序序列团簇态作为量子信道;在确定量子信道的安全性以后,Alice制备编码量子态(Bell态)序列,然后通过对自己手中的粒子进行Bell基测量,接着Charlie对自己手中的粒子进行单粒子的测量,就能把信息传送给接收者Bob;最后,Bob测量自己手中的粒子,并通过分析三人的测量结果,从而获得Alice要传送的信息.在我们提出的方案中,携带信息的粒子不需要在公共信道上传输.该文中,我们给出了方案的安全性分析,证明了我们的方案是决定性的和安全的.在未来,我们的方案在以目前的实验技术为基础条件下很可能得到实现.
[Abstract]:A controllable quantum secure direct communication scheme based on five-particle cluster state is proposed. In this scheme, the information sender Alice, information receiver Bob and the controller Charlie share an ordered sequence cluster state prepared by Alice as the quantum channel; after determining the security of the quantum channel, Alice prepares the encoded quantum state (Bell state) sequence, and then carries on the Bell basis measurement to the particle in his own hand, and then Charlie carries on the single particle measurement to the recipient Bob;, and then transmits the information to the receiver Bob;. Finally, Bob measures the particles in his hand and obtains the information to be transmitted by Alice by analyzing the measurement results of three people. In our proposed scheme, particles carrying information do not need to be transmitted over the public channel. In this paper, we give the security analysis of the scheme, and prove that our scheme is decisive and secure. In the future, our scheme is likely to be implemented on the basis of the current experimental technology.
