摘要
利用了高维Bell态,设计一种新的量子投票方案.方案分为4个阶段:首先,高维Bell纠缠态粒子被作为投票信息载体被分发给投票者;然后投票者利用最小复杂度搜索寻找竞选者,并用相移操作投出选票;接着代理人收到选票后,运用纠缠交换过程来检测窃听,通过检查粒子的测量结果来发现是否非法攻击;最后代理人利用计票算子统计票数并公布.所有人都只知道总的投票结果,单个投票者的投票信息是保密的.协议分析了各种攻击下的抵抗,证明了这是一个合理,安全,高效的量子投票方案.
Abstract：Motivated by high-dimensional Bell states entanglement swapping, a novel quantum distributed ballot scheme is proposed. The protocol includes four steps. The entanglement is distributed over separated voter＇s sites. The voters search the desired states by minimal complexity. The ballot information is encoded by phase shifting operations performed on the particles of entangled Bell states, which ensures the security present scheme. The checking phase is designed in detail based on entanglement swapping. The counting phase is completed by tallyman. The security of these protocols with respect to various kinds of attack is discussed. Key words： voting; high-dimensional bell states; entanglement swapping; phase shift operation
