    "abstract": "Optimal procedures play an important role in quantum information. It turns\nout that some naturally occurring processes like emission of light from an atom\ncan realize optimal transformations. Here we study how arbitrary symmetric\nstates of a number of d-level systems can be cloned using a multilevel atomic\nsystem. It is shown that optimality is always ensured even though the output\nnumber of systems is probabilistic.",
