浅谈量子克隆

Introduction of Quantum Cloning

量子态不可克隆体现了量子力学的固有特性,它是量子信息科学的重要基础之一。文章简要介绍了量子不可克隆定理,量子非精确克隆,以及量子克隆在量子通信方面的应用,最后指出量子克隆研究的意义所在。

That an unknown quantum states cannot be cloned perfectly is the inherent characteristic of quantum mechanics. It is one of the most important basis of quantum information science. In this paper,we briefly introduces the No-Cloning Theorem,quantum copying and the application of quantum copying.The paper end with a conclusion.
