Anonymous quantum voting protocol based on Chinese remainder theorem


Electronic voting is an essential tool in modern society. In this paper, we investigate anonymous quantum voting for the travelling ballot. At present, there exist some anonymous quantum travelling ballot protocols, but these protocols are not practical because of the lack of non-reusability or verifiability. Based on Chinese Remainder Theorem, an anonymous quantum voting protocol of the travelling ballot is proposed with an entanglement state, where the partial qubits of the entangled state as the quantum ballot are sent to each voter one-by-one and the other as the corresponding quantum certificate to the tallyman. The proposed protocol can not only ensure non-reusability but also can verify the correctness of the votes.

Graphic Abstract

(1) Define phase operators as voting operators based on Chinese Remainder Theorem; (2) Present an anonymous quantum voting protocol for the travelling ballot; (3) Meet more security requirements, e.g., verifiability, non-reusability and anonymity.
