    "abstract": "We investigate the asymmetric Gaussian cloning of coherent states which\nproduces M copies from N input replicas, such that the fidelity of all copies\nmay be different. We show that the optimal asymmetric Gaussian cloning can be\nperformed with a single phase-insensitive amplifier and an array of beam\nsplitters. We obtain a simple analytical expression characterizing the set of\noptimal asymmetric Gaussian cloning machines.",
