Abstract
We propose a quantum voting scheme with Greenberger-Horne-Zeilinger (GHZ) states. In this scheme, quantum sequences that are formed by different particles of different GHZ states are sent to other participants respectively. Because of the correlation of different particles in a GHZ state, different participants perform a same measurement on each particle in the sequence that they received in order to obtain a same measurement outcome. To reduce the overhead of quantum transmissions, the participants publish their results on a bulletin board. According to the information on the bulletin board, voters can check whether their voting information is correct. If an attacker tampers with the voting information, his behavior can be discovered during the verification process. Analyses show that our new scheme has high efficiency and can withstand all the known attacks.
