    "abstract": "We investigate the optimal distribution of quantum information over\nmultipartite systems in asymmetric settings. We introduce cloning\ntransformations that take $N$ identical replicas of a pure state in any\ndimension as input, and yield a collection of clones with non-identical\nfidelities. As an example, if the clones are partitioned into a set of $M_A$\nclones with fidelity $F^A$ and another set of $M_B$ clones with fidelity $F^B$,\nthe trade-off between these fidelities is analyzed, and particular cases of\noptimal $N \\to M_A+M_B$ cloning machines are exhibited. We also present an\noptimal $1 \\to 1+1+1$ cloning machine, which is the first known example of a\ntripartite fully asymmetric cloner. Finally, it is shown how these cloning\nmachines can be optically realized.",
