Application Prospects

A novel controlled bidirectional quantum secure direct communication (CBQSDC) protocol based on Grover’s algorithm is proposed in our paper, which is on the basis of investigating the properties of it. To avoid information leakage, the strategy of adding control-not gate is employed in our protocol. The proposed protocol uses Bell state as quantum resource to transmit information in a dual-quantum-channel. Through the proposed measures, we can not only prevent information leakage, but also improve the efficiency of transmission. As can be shown from the security analysis, the Grover’s algorithm has great application prospects in the research of CBQSDC.
