    "abstract": "We show that optimal universal quantum cloning can be realized via stimulated\nemission. Universality of the cloning procedure is achieved by choosing systems\nthat have appropriate symmetries. We first discuss a scheme based on stimulated\nemission in certain three-level-systems, e.g. atoms in a cavity. Then we\npresent a way of realizing optimal universal cloning based on stimulated\nparametric down-conversion. This scheme also implements the optimal universal\nNOT operation.",
