摘要
量子特性在信息领域有着独特的功能,在提高运算速度、确保信息安全、增大信息容量和提高检测精度等方面有望突破现有经典信息系统的极限。量子信息科学正是由量子力学与信息科学相结合的一门学科。近年来量子信息在理论、实验和应用领域都取得重要突破。量子通信在一定程度上已经实现了商业应用并具有广阔的市场应用前景;量子计算机具有目前的计算机从原理上所不可能具有的无与伦比的威力,但目前尚未真正意义上的量子处理器的技术实现,基于量子光学和固态体系的量子处理器的研究大有可为。
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 theo- retical, 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 cur- rent 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.
