The quantum cryptography employing entangled photons is demonstrated using three optical ground stations in Europe. There is a possibility for Japan to join it as one of the optical ground stations for the quantum key distribution. In this paper, the overview of the SPACEQUEST project is introduced, and the research and development of space quantum cryptography communications in Japan is discussed., 形態: カラー図版あり, 共催: 日本学術会議, Physical characteristics: Original contains color illustrations, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113038}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {日本における宇宙量子暗号通信の研究開発について}, volume = {22}, year = {2006} }
