摘　　要： 量子不可克隆定理是基于量子态的叠加原理,但是该定理的证明过于简单,并没有排除所有可能的克隆情况,证明过程中有些环节没有详细论证。而量子力学本来是非常复杂的理论,互补原理也说明不能采用一种思路来说明一切问题。从科学的发展史来看,许多在一定阶段不可能的事,比如测量和复制,在对微观或者深入的属性了解后就往往就能实现测量、复制。假如通过间接的测量或者更加微观的特性能进行测量量子态,则能成功进行量子态的克隆。量子力学中的波粒二象性、不确定性关系等等难于理解,但是却与人类社会中的许多现象绝妙地类似,从更加微观的角度分析,如果量子态也存在类似基因的成分,可以绕开量子不可克隆定理的证明中假定的情况进行克隆。 The paper queries correctness of quantum no-cloning theorem that is very imporant in the quantum information technology and the whole quantum mechanics.The proof of quantum no-cloning theorem is very simple and it can’t exclude all kinds of possible cloning.Some parts of the proof are doubtful and not very clearly proved.While quantum mechanics is very complex and not completely known,the principle of complementarity shows that it is incorrect to explain everything in a simple way.The development of science tells us many things such as measurement and copy of a particle that are thought to be impossible in a stage,may be possible when the more profound,precise and tiny characteristics is found out.If it is possible to measure in an indirect way that can’t change the measured quantum state,the quantum cloning is possible.The wave-particle duality and uncertainty relation in quantum mechanics are very hard to imagine,but they are very similar to the phenomenon of the society and human in which copy and cloning is possible.If the quantum state has something like gene,it is possible to cloning a quantum state.
