| Abstract;The computer's history originated with ENIAC in 1945 and reached the quantum computer after many changes. The history of the quantum computer start with a lecture by Professor Feynman in 1959 followed by researches of computing models, algorithms etc. Experimental research was begun in 1990s. The feature of the quantum computer is ability to execute huge computing in very short time. The principle of the quantum computer, whose keywords are "superposition" and "tangling", is briefly explained. The arithmetic circuit developed by NEC is introduced. This consists of Josephson's junctions, and 2 quantum bits has been realized, but larger quantum bits can be realized theoretically. NEC plans to make practical quantum computers in about 2010. |
