This protocol achieves the functionality of [[Quantum Cloning]]. Asymmetric universal cloning refers to a quantum cloning machine (QCM) where its output clones are not the same or in other words, they have different [[fidelities]]. Here we focus on <math>1 \rightarrow 1 + 1</math> universal cloning. In asymmetric cloning, we try to distribute information unequally among the copies. A trade-off relation exists between the fidelities, meaning if one of the copies are very close to the original state, the other one will be far from it. There are two approaches to this kind of cloning, both leading to same trade-off relation. Here we discuss the quantum circuit approach (Buzek et al., 1997) It can be also noted that the symmetric universal <math>1 \rightarrow 2</math> cloning can be considered as a special case of the asymmetric universal cloning where the information between copies has been equally distributed.
