提出了量子直接通信，包括确定性安全量子通信和基于双量子位量子搜索算法的量子安全直接通信协议。秘密信息采用双量子位一元运算编码，由通信双方直接交换。讨论了在拦截重发攻击和个体攻击下协议的安全性。我们发现，协议是安全的窃听攻击。
Quantum direct communications, including deterministic secure quantum communication and quantum secure direct communication protocol using two-qubit quantum search algorithm are proposed in this paper. Secret messages are encoded by two-qubit unitary operations and exchanged by the two communication parties directly. We discussed the security of the protocol under intercept-resend attack and individual attack. We found that the protocols are secure against eavesdropping attacks.
