    "abstract": "We propose two feasible experimental implementations of an optimal asymmetric\n1-\u003e2 quantum cloning of a polarization state of photon. Both implementations\nare based on a partial and optimal reverse of recent conditional symmetrical\nquantum cloning experiments. The reversion procedure is performed only by a\nlocal measurement of one from the clones and ancilla followed by a local\noperation on the other clone. The local measurement consists only of a single\nunbalanced beam splitter followed in one output by a single photon detector and\nthe asymmetry of fidelities in the cloning is controlled by a reflectivity of\nthe beam splitter.",
