Abstract: In order to promote the automation of quantum communication platform, the software part in quantum key distribution(QKD)layer is designed and investigated. Based on experimental operation, the experimental process is encapsulated by writing friendly visual interface for beginners, which reduces the requirement of user’s programming level. The experimental optical path control in the platform is divided into three parts, MFC, Labview and FPGA. The three parts cooperate with each other to realize phase self-scanning which integrates control, scanning and judgment. Based on the designed optical path and software, quantum communication automatic operation platform is built, and the scanning stability is experimentally proved.

Key words: quantum communication, quantum key distribution, quantum optics, optical communication
