一种基于GHZ-like态的量子匿名投票协议OA

In response to the prevalent issue of low voting efficiency in existing quantum distributed voting protocols,a quantum anonymous voting protocol is proposed,leveraging the unique entanglement properties of three-particle GHZ-like states.The steps of the whole process of this quantum voting protocol are illustrated with examples.Finally,the security and efficiency of the protocol are analyzed.The proposed protocol uses the GHZ-like state as the quantum entangled state required by the voting protocol,and voters only need to perform unitary operations on single-particle,which reduces the requirements on the equipment and capabilities of partici-pants.And the whole voting process is under the supervision of a third-party supervisor,so as to achieve anony-mous voting.The research results show that the protocol can resist both external eavesdropping attacks and dishon-est voters'multiple voting behaviors,with the voting efficiency significantly improved.
