| Popis: | We propose an experimentally feasible scheme for implementing controlled quantum secure direct communication by using six-qubit entangled states. According to the results measured by the sender and the controller, the receiver can obtain different secret messages in a deterministic way with unit successful probability. In our scheme, the information-carrying qubits do not need to be transmitted over the public channel. Therefore, the scheme is determinate and secure. |
