    "abstract": "A transformation achieving the optimal symmetric N-to-M cloning of coherent\nstates is presented. Its implementation only requires a phase-insensitive\nlinear amplifier and a network of beam splitters. An experimental demonstration\nof this continuous-variable cloner should therefore be in the scope of current\ntechnology. The link between optimal quantum cloning and optimal amplification\nof quantum states is also pointed out.",
