Quantum Voting Protocol Based on Quantum Fourier Transform Summation

Abstract

To solve the problem that the user information is easy to be stolen in the traditional electronic voting,and the existing quantum voting generally has low computational efficiency,a quantum voting protocol based on the combination of quantum Fourier transform summation and vector coding is proposed.In the protocol,each particpant uses quantum Fourier transform to entangle their secret values into the hands of the initiator in the form of a single particle state to vote,and the secret ranking of candidates’ votes is realized by vector coding,finally the winner announces the number of votes and ranking.The correctness of the quantum Fourier transform summation in the protocol is verified by the quantum computing simulator provided by IBM.Through theoretical analysis,it is proved that the protocol has good security against four kinds of attacks which are intercept-resend attack,entanglement measurement attack,collusion attack,monitor and candidate attack,and the efficiency of the protocol is higher than the existing quantum voting schemes of the same type.
