摘　　要：为了解决当前部分量子投票协议中大量使用制备复杂的纠缠资源及操作困难的纠缠态测量,从而导致可实现性差的问题,文章基于量子行走公钥加密设计电子投票方案,量子行走可以在粒子之间产生任意形式的纠缠,并避免纠缠态测量。初始时仅需制备单粒子,若干步量子行走后再对其实施单粒子测量,即可以实现所提方案。文章中使用的量子行走技术已在多种系统上实现,安全性分析表明,该方案可以实现信息论安全,当前技术下可行且安全。文章方案仅使用1个粒子表示n位投票信息,效率高于现有方案。In order to solve the problem of poor realizability to prepare complex entanglement resources and perform difficult entanglement state measurements in current quantum voting protocols,this paper designed an electronic voting scheme based on public key encryption of quantum walks.Quantum walks can generate any form of entanglement between particles and avoid entanglement state measurements,and therefore,the proposed solution can be achieved by initially preparing single particles and finally performing single-particle measurements.The quantum walks has been implemented on a variety of systems.In addition,the security analysis shows that the proposed scheme can achieve information-theoretical security.So,it is feasible and secure under current technology.This paper uses one particle to represent n-bit voting information,efficiency higher than existing solutions.
