Abstract

Objectives: A novel quantum binary voting scheme that uses only single qubits is proposed. Specifically, the protocol is designed by modifying a single qubit based scheme for controlled deterministic secure quantum communication. Methods/ Statistical Analysis: The security of the protocol is analyzed over some specific attacks. Further, qubit efficiency of the protocol is also calculated. Findings: It is established that in the case of binary voting, the proposed single qubit based quantum voting protocol is more efficient than some of the recently proposed protocols for binary voting. Further, it is also shown in some of the recent papers that the original single qubit based quantum secure direct communication scheme that has been modified to design the proposed quantum voting scheme is less affected than corresponding multiqubit based scheme. This further establishes the relevance of the present results. Application/Improvements: As the proposed scheme does not require complex quantum resource like entanglement & qudits, it seems to be experimentally realizable using the available technology.
