To establish Secure Photonic Network based on the QKD technology, the basic performance enhancement and stability improvement of the QKD system are necessary. In addition, to enlarge application areas of Secure Photonic Network, an interfacing function for secure keys shared among multiple user terminals should be developed. To this end, we pursue the following two subthemes.
