Quantum mechanics and physics have become important sources for developing ultimately secure communication in the form of quantum cryptography and an extremely powerful computer called a quantum computer. Cutting-edge nanofabrication technologies, highly accurate measurements, and a deep understanding of quantum information science are necessary to control quantum systems arbitrarily and to advance the research on quantum information technology (QIT) toward quantum cryptography and quantum computers. This paper summarizes the present status and future expectations of QIT and describes some recent activities in NTT Laboratories.
