Quantum property which has its particular function in the information filed is expected to break the limitation of current classical information system in the aspects of promoting operation speed, insuring information security, improving information capacity, and promoting detection accuracy. The quantum information science is a subject that combines the quantum mechanics with the information science. The quantum information has made important breakthroughs in the theoretical, experimental, and application fields in recent years. To a certain degree, the quantum communication has already realized the commercial application with bight market prospect. The quantum computer has its incomparable power that current computer does not possess theoretically. However, the real technology of quantum processor has not been realized at present, and the research on the quantum processor based on quantum optics and solid system has a rosy future.
