    "abstract": "A scheme for optimal Gaussian cloning of optical coherent states is proposed\nand experimentally demonstrated. Its optical realization is based entirely on\nsimple linear optical elements and homodyne detection. The optimality of the\npresented scheme is only limited by detection inefficiencies. Experimentally we\nachieved a cloning fidelity of about 65%, which almost touches the optimal\nvalue of 2/3.",
