Voting security is crucial for preventing fraud, maintaining public trust, and is a cornerstone of democratic governance. The development of large-scale quantum computers opens the possibility of efficiently solving advanced voting protocols and improving voting security.

The Lukin Lab at Harvard has leveraged quantum networks and developed protocols for information-theoretic security in a resource-efficient manner. This approach encodes ballot information in quantum states, significantly reducing communication complexity compared to classical computing methods, and proposes a secure anonymous queuing protocol. The scheme's efficiency and noise robustness make it suitable for implementation in practical quantum networks, offering a novel solution to authentication and vote encoding, with applications for governments and companies seeking secure communication for voting.
