High-Fidelity Teleportation beyond the No-Cloning Limit and Entanglement Swapping for Continuous Variables

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