Abstract
In order to improve eavesdropping detection efficiency, we propose a quantum secure direct communication and authentication protocol based on three-particle asymmetric entangled state and design an efficient quantum circuit for implementing the protocol. This protocol has two modes, in message mode, a qubit is used to transmit two bits classical information based on a Bell state, in control mode, three-particle asymmetric entangled state is inserted into the particle flow for detecting eavesdropper. Eavesdropping detection efficiency is got by calculating the relationship between the amount of information and detection probability, if eavesdroppers want to obtain all information, detection probability is 63%, the analysis results indicate that this proposal is more secure than other quantum secure direct communication protocol.
