    "abstract": "We propose an optical implementation of the Gaussian continuous-variable\nquantum cloning machines. We construct a symmetric N -\u003e M cloner which\noptimally clones coherent states and we also provide an explicit design of an\nasymmetric 1 -\u003e 2 cloning machine. All proposed cloning devices can be built\nfrom just a single non-degenerate optical parametric amplifier and several beam\nsplitters.",
