摘　　要：量子信息学是物理学与信息学交叉而形成的一门新兴学科。论述了其建立的理论基础——量子态的纠缠现象,介绍了量子计算机、量子密钥、量子隐形传态等相关高新技术,分析了今后的研究方向,以期对该学科有全面的了解。Quantum information theory is a new research area which is related with both quantum physics and information theory. After discussing its theoretical basis： quantum entanglement, we in- troduce some advanced technologies such as quantum computer, quantum cryptosystem and quantum teleportation etc. The further researches in this direction is also analyzed so that we can grasp this subject more completely.

关 键 词：量子信息学 纠缠度 量子计算机 量子密钥
