量子相干性和量子纠缠等特性为量子计算带来了完全不同于经典计算的独特运算方式，量子计算表现出的并行性更是令经典运算望尘莫及。Shor 算法的提出完全展示了量子算法在解决某些经典问题时的优势，接踵而至的Grover 搜索算法进一步诠释了量子计算的威力。此后，算法“量子化”在国际上掀起了研究的热潮，尤其在量子智能算法方面取得了不错的成果。文章首先介绍量子计算的发展现状和基本原理；然后列举三种典型的量子算法，展示量子计算的优越性；最后介绍该领域的研究进展。
According to quantum mechanics, quantum state has many advantages of the coherence and entanglement and the inner parallelism of quantum algorithm is totally different from the classical algorithm. Shor's algorithm shows the advantage of quantum algorithm in solving some classical Non-polynomial problems, then Grover's search algorithm further proves this point. And this brought more and more research on quantum algorithm in many countries and they have got great achievements especially on quantum intelligent algorithm. In this paper, the development and fundamental principles of quantum computing are generalized, then three typical quantum algorithms is introduced, and the superiority of quantum computer is explained. Finally, current research of quantum computation are introduced.
