摘要：

基于受控量子安全直接通信（CQSDC），提出了一种GHZ-like态的量子投票协议。在所提协议中，监督员Charlie负责建立GHZ-like量子信道，并监督投票者Alice和计票员Bob的行为。Alice根据投票规则和自己的意愿进行投票。Bob在Charlie的帮助下破译投票结果并对其进行计数。所提协议不需要量子态作为票传输于Alice和Bob之间，只需测量自己拥有的粒子，再将信息通过经典比特传输。与其他量子投票协议相比，所提协议充分利用了CQSDC和纠缠交换的原理，显著提高了投票效率。

Abstract:

Based on the controlled quantum secure direct communication (CQSDC), a quantum voting protocol with Greenberger-Home-Zeilinger-like state is proposed. In the proposed protocol, the supervisor, Charlie, is responsible for establishing GHZ-like quantum channels, and supervises the behavior of the voter, Alice, and the teller, Bob. Alice generates and sends out the vote according to the voting rules and her own wishes, and Bob decodes the vote and counts it with the help of Charlie. The proposed protocol does not require a quantum state to be transmitted between Alice and Bob as a ticket, simply measuring the particles it owns and transmitting the information through the classic bits. Compared with other quantum voting protocols, the proposed protocol makes full use of the CQSDC and entanglement swapping principle, and it improves the voting efficiency significantly.

Key words: quantum optics, quantum voting, entanglement exchange, controlled quantum secure direct communication, GHZ-like state
