*'''Approximate cloning protocols for discrete quantum systems''' Cloning protocols for [[discrete quantum systems (DV)]] have been included in this section. The simple case of copying a qubit is an example of these cloning machines. The more general case of these quantum cloning machines is N <math>\rightarrow</math> M cloner which will produce M identical copies of N initial states. The discrete quantum cloning machines can be divided into two main categories: universal and non-universal. | *'''Approximate cloning protocols for discrete quantum systems''' Cloning protocols for [[discrete quantum systems (DV)]] have been included in this section.

These protocols produce copies which are approximately close to the original state at every round.
