摘　　要：针对现有量子分配式投票协议中存在投票效率普遍偏低的情况,利用三粒子GHZ-like态的纠缠特性提出一种量子匿名投票协议;结合实例,阐述量子投票协议整个过程的步骤;最后对该协议的安全性和效率进行分析.该协议采用GHZ-like态作为投票协议所需的量子纠缠态,投票者只需要对单粒子进行酉操作,降低了对参与者设备和能力的要求;且整个投票过程都在第三方监督者的监督下,实现了匿名投票.研究结果表明,该协议能够同时抵御外部窃听攻击和不诚实投票者的多次投票行为,且投票效率显著提高.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 participants.And the whole voting process is under the supervision of a third-party supervisor,so as to achieve anonymous voting.The research results show that the protocol can resist both external eavesdropping attacks and dishonest voters'multiple voting behaviors,with the voting efficiency significantly improved.
