In such systems, the vehicle to transfer quantum information is a single photon, however, the transmission distance is limited by the absorption of photons in an optical fiber in which the maximum demonstrated range is about 100 km. Free-space quantum cryptography between a ground station and a satellite will be a possible solution to send the quantum information beyond further distances than that with optical fibers since there is no birefringence effect in the atmosphere. At the National Institute of Information and Communications Technology (NICT), the laser communication demonstration between the NICT optical ground station and a low earth orbit satellite was successfully conducted in 2006. For such space communication links, the free-space quantum cryptography is considered to be an important application in the future. A prototype system for free-space quantum cryptography using weak coherent pulse sources and a telecom communication channel is developed. The preliminary results are presented.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
