This protocol achieves the functionality of [[Quantum Cloning]]. A state-dependent cloner is a Quantum Cloning Machine (QCM) which is dependent on the input states. The main purpose of a state-dependent cloner is to design a QCM which produces better copies (compared to the universal QCMs) by having some partial information about the input states. We investigate the general $N \rightarrow M$ approximate state-dependent cloner which transforms two set of non-orthogonal states (consisting of N states) to M identical clones with a special constraint on the inner product of the final states. For the special case of $1 \rightarrow 2$ cloner, it is shown that, in general, this machine acts much better than the [[Quantum Cloning#Protocols|universal cloning]] protocol for two special set of states.
