Anonymous voting for multi dimensional CV quantum system*
We investigate the design of anonymous voting protocols, CV based binary valued ballot and CV based multi valued ballot with continuous variables (CV) in a multi dimensional quantum cryptosystem to ensure the security of voting procedure and data privacy. The quantum entangled states are employed in the continuous variable quantum system to carry the voting information and assist information transmission, which takes the advantage of the GHZ like states in terms of improving the utilization of quantum states by decreasing the number of required quantum states. It provides a potential approach to achieve the efficient quantum anonymous voting with high transmission security, especially in large scale votes.
