摘要：

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.
