A Practical Multi-candidate Voting Protocol on Quantum Blockchain Adapted for Various Tally Principles
摘要
Quantum secure voting aims to provide various approaches to performing electronic voting via quantum technologies, like entangled particles or quantum key distribution, so as to guarantee the security of the voting procedures against forthcoming quantum computers. Beyond the widely studied two-candidate vote, this paper steps to the multi-candidate case. Based on quantum blockchain and quantum secure communication, a class of relatively simple voting protocols is designed. They satisfy several paramount properties regarding secure voting protocols. These protocols can be implemented using presently available technology. Moreover, they show great potential in tallying ballots with respect to different principles, such as Borda rules and maximal lotteries.
