Abstract
- Frequency entangled state originated from optical frequency comb (OFC) is an important quantum source for quantum communication. In this paper, we propose a traveling quantum anonymous voting (TQAV) protocol, which employs a monolithic microresonator with cascaded four-wave mixing (FWM) to prepare continuous-variable frequency entanglement sources. Multi-pair EPR entangled states and five-partite entangled states generated from the degenerate and nondegenerate FWM process are used as signal sources for the TQAV to characterize different candidates. Voters are able to vote for their preferred candidates by performing displacement operations on the received modes, and the ballot agency can judge the voting result according to the measurements. The entanglement property of the quantum state is utilized to keep voters away from the voting results. The security of the protocol under collective attacks and spectroscopic noise attacks is guaranteed by the security mechanism of continuous-variable quantum key distribution. Our results provide a reference for the application of OFC in multiparty quantum communication. [ABSTRACT FROM AUTHOR]
