Controlling the flow of information in quantum cloners: Asymmetric cloning
V. Buzek, M. Hillery, R. Bednik
We show that the distribution of information at the output of the quantum cloner can be efficiently controlled via preparation of the quantum cloner. We present a universal cloning…

Universal optimal cloning of qubits and quantum registers
Vladimir Buzek, Mark Hillery
We review our recent work on the universal (i.e. input state independent) optimal quantum copying (cloning) of qubits. We present unitary transformations which describe the optimal…
