*'''Probabilistic Cloning''' Another way of having an imperfect cloner is to have a probabilistic cloning machine will produce the copies with some probability of success. In these protocols coping task can succeed with probability, but if it is successful, we can always obtain perfect copie. The probabilistic cloning machines will no longer consists of unitary operations only. But these machines are represented by quantum maps instead. This quantum cloning machine is useful, in particular, in studying the B92 quantum key distribution protocol. | *'''Probabilistic Cloning''' Another way of having an imperfect cloner is to have a probabilistic cloning machine will produce the copies with some probability of success.
