Guihua Zeng · Information Security and Communications Privacy · 2009
This paper discusses in detail the principle of the optical devices in both continuous and discrete variable quantum key distribution,including the classical QKD communication system. A circuit control module using Xilinx Corporation's ML405 Evaluation Platform and suitable for various QKD experiments is proposed. The controller generates necessary nanosecond clock signals for optical devices and integrates quantum cryptography communication system. Finally,the design flow is implemented by downloading the bit stream,which is generated by the Embedded Software ISE9.1i and EDK9.1i,into FPGA chip,and completely meets the needs of the experiment.
