    "abstract": "We experimentally demonstrate continuous-variable quantum teleportation\nbeyond the no-cloning limit. We teleport a coherent state and achieve the\nfidelity of 0.70$\\pm$0.02 that surpasses the no-cloning limit of 2/3.\nSurpassing the limit is necessary to transfer the nonclassicality of an input\nquantum state. By using our high-fidelity teleporter, we demonstrate\nentanglement swapping, namely teleportation of quantum entanglement, as an\nexample of transfer of nonclassicality.",
