A Secure Quantum Voting Scheme Based on Orthogonal Product States

As an important topic of quantum cryptography, quantum voting has attracted more and more attention in recent years. In this paper, we propose a quantum voting scheme based on a new set of orthogonal product states. Since different particles in the same orthogonal product state are transmitted separately, the security of the vote message in the scheme can be protected. The availability and security analysis show that the scheme satisfies the basic properties of voting can resist known quantum attacks. Furthermore, our scheme solves the problem of difficult preparation of entangled states in actual situations and improves the practicability of voting scheme. We hoped that our research will provide new ideas for the further study of quantum voting.
