Summary:On the basis of studying quantum dialogue (QD) protocols and controlled quantum dialogue (CQD) protocols, this paper creatively proposes a controlled and authenticated quantum dialogue (CAQD) protocol based on Grover’s algorithm. The protocol uses two-particle state as quantum resources to bidirectionally transmit information in the channel. Applying the properties of Grover’s algorithm in two-qubits to the target state search process of this CAQD protocol, which can realize the transmission of two bits information between communication parties. In addition, an identity authentication step is added to the communication process, effectively solving the problem of eavesdropping that existed in the past. Compared with the existing protocols of the same type, this protocol has better advantages.
