Quantum Information Science Research Center is moving ahead with research in new technologies that will completely surpass the functionality and ability of current leading edge science represented by fiber communications and high speed computers. In particular, experimental research to realize and develop new theories that support the realization of quantum encrypted communication and quantum computers based on the basic phenomenon of quantum mechanics. The research center has hosted the major conference in this field, International Conference on Quantum Communication, Measurement, and Computing: QCM&C. The photo shows the new quantum encrypted communication system, the Quantum Stream Cipher, invented by this center based on optical communications. Research Center for Quantum Information Science
