    Abstract

    Based on the controlled quantum secure direct communication(CQSDC), a quantum voting protocol with Greenberger-Horne-Zeilinger(GHZ)-like state is proposed. In the proposed protocol, the supervisor Charlie is responsible for establishing GHZ-like quantum channels and supervising 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, only measuring the owned particles 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.
