A Generic Reconfigurable System With High-Speed Data Transmission and High-Precision Time Measurements Applied to a Quantum Bit Commitment Experiment.

A reconfigurable system with high-speed data transmission and high-precision time measurement capability based on optical fiber and FPGA technology is presented in this paper. The design is generic for applications where data transmission and time measurement are required. This could be adapted to particle physic experiment, large imaging system, quantum bit commitment, etc. The system is extendable and reconfigurable, allowing data transmission in a bandwidth of 7.5 Gbps. TDC-GPX for time measurement, signal conditioning, data storage, real-time data processing with an FPGA with standard interface such as USB 2.0 and an expansion interface are included. As an example of an application, the design for bit commitment experiment is fully introduced. [ABSTRACT FROM PUBLISHER]
