For example, we cannot copy an unknown state exactly because of "the no-cloning theorem"(no-deleting theorem), which is known as one of the most significant differences between classical and quantum information. Therefore to get to know what we can and cannot do in QIS or in quantum physics becomes an important and interesting problem. Particularly, in quantum communication and quantum cryptography, many novel schemes are based on the fact that nonorthogonal states cannot be discriminated determinately.
例如，经典信息中，编码状态是可以精确复制、区分的；而在量子信息中，由于叠加性的存在，使得非正交态不可区分，量子态不可复制、删除等；故而以往既成的观念都被打破，探讨在量子信息的框架下编码信息的估计、物理可实现的操作，以及这些量子体系在外界通过物理方法进行识别过程中的差异，是量子信息学、乃至物理学中的重要也很基本的问题。

principal quantum number：主量子数
量子化条件要求电子绕核运动的角动量不能取任意值,只能取约化普朗克常数的整数倍. 这表明稳态氢原子的能量可取值也不能连续变化,而只能取某些分立的值. 按照这个理论模型,稳态氢原子的能量是负的,并且与主量子数(principal quantum number)的平方成反比.
