Electronic voting, the use of electronic systems to cast, record or count votes, could potentially simplify the process of electing new political leaders or other representatives. While some countries have already started using internet-connected devices or electronic voting machines at polling stations, the trustworthiness, security and anonymity of electronic voting systems are still widely debated.

Two distinct research teams, based at Sorbonne University and at the University of Geneva, recently carried out similar experiments assessing the potential of quantum physics-informed electronic voting protocols. The results of their tests, both published in Physical Review Letters, indicate that quantum protocols could allow votes to be collected electronically while protecting voter anonymity, without relying on a trusted central election authority.
