在经典信息理论中,编码状态可以精确复制与区分;而在量子信息中,由于态的叠加性存在,使得非正交态不可区分,量子态不可复制与删除。但是,量子态的区分和克隆在新型的量子信息科学中具有广泛的应用,例如量子密码的接收和窃听等。本文简要介绍量子态的区分和克隆的数学概念及相关研究结果。

In the classical information theory,coding state can be accurately copied and distin-guished;while in quantum information,it is impossible to copy,delete and distinguish non-or-thogonal states due to the superposition of states.However,discrimination and cloning of quan-tum states have extensive applications in the new-type quantum information science such as re-ceiving and eavesdropping in the quantum cryptography and so on.In this review paper,the mathematical concepts and the related research results about discrimination and cloning of quan-tum states are briefly introduced.
