Based on quantum entanglement, secure anonymous ballot systems are introduced to realize voting among numerous candidates in this paper. By searching individuals, each voter may cast a vote for his desired candidates of which number may be more than one. Therefore, the system based on the proposed algorithm may be applied voting among many candidates, such as a network ballot with the development of a quantum network. Finally, the security of the present scheme is investigated.

Key words: quantum voting system, multi-object ballot, quantum entangled states, quantum network, security and anonymity
