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。

Magnetic properties of a series of Cd1-xMnxSe quantum dots with different sizes and Mn concentrations were measured by using superconducting quantum interference device magnetometer.

我们利用超导量子干涉仪量测不同尺度(D = 5 nm， 8 nm)及不同Mn浓度(x = 0.375%， 0.75%， 1.5%)的Cd1-xMnxSe奈米颗粒磁性；我们推测在温度2 K下，所量测的磁化强度是由Mn原子贡献而非来自奈米颗粒，拟合其磁化强度对磁场曲线图而得出样品中Mn原子个数，同时假设Mn离子的磁性行为高达室温仍满足Brillouin function和Curie顺磁定律，所以可从高温的数据扣除Mn的顺磁贡献。
