Contribution

It presents a novel quantum election scheme that does not require entanglement and guarantees security properties under realistic quantum channel conditions.

Findings

Ensures privacy, fairness, and verifiability in large-scale elections.

Operates securely despite quantum channel loss and errors.

Does not depend on entanglement, simplifying implementation.

Abstract

An unconditionally secure authority-certified anonymous quantum key distribution scheme using conjugate coding is presented, base on which we construct a quantum election scheme without the help of entanglement state. We show that this election scheme ensures the completeness, soundness, privacy, eligibility, unreusability, fairness and verifiability of a large-scale election in which the administrator and counter are semi-honest. This election scheme can work even if there exist loss and errors in quantum channels. In addition, any irregularity in this scheme is sensible.
