# Quantum anonymous voting with anonymity check

## TL;DR

This paper introduces a quantum anonymous voting protocol that ensures unconditional voter privacy and allows voters to verify the anonymity of the process through entanglement checks, preventing cheating by the tallyman.

## Contribution

It presents a novel quantum voting protocol where ballots are returned for verification, enhancing security and transparency over previous methods.

## Key findings

- The protocol guarantees unconditional voter privacy.
- Cheating attempts by the tallyman can be detected through entanglement destruction.
- Voters can verify the integrity of the vote counting process.

## Abstract

We propose a new protocol for quantum anonymous voting having serious advantages over the existing protocols: it protects both the voters from a curious tallyman and all the participants from a dishonest voter in unconditional way. The central idea of the protocol is that the ballots are given back to the voters after the voting process, which gives a possibility for two voters to check the anonymity of the vote counting process by preparing a special entangled state of two ballots. Any attempt of cheating from the side of the tallyman results in destroying the entanglement, which can be detected by the voters.
