Description
Summary:This paper presents a novel quantum private comparision ( Q P C ) protocol based on the single-qubit rotations, quantum SWAP-test and quantum SWAP gates. The proposed QPC protocol can secretly compare information of the two participants without the help of a third party ( T P ). The security analysis of the presented QPC protocol shows that it is quantum indistinguishable and information theory security for all outside attackers and inside attackers. Finally, we compare some important features of the presented QPC protocol with other QPC protocols. The results show that the proposed protocol has some advantages different from previous protocols.
