    "abstract": "We investigate the universal asymmetric cloning of states in a Hilbert space\nof arbitrary dimension. We derive the class of optimal and fully asymmetric\n1-\u003e3 cloners, which produce three copies, each having a different fidelity. A\nsimple parametric expression for the maximum achievable cloning fidelity\ntriplets is then provided. As a side-product, we also prove the optimality of\nthe 1-\u003e2 asymmetric cloning machines that have been proposed in the literature.",
