    "abstract": "We study the Braunstein-Kimble setup for teleportation of quantum state of a\nsingle mode of optical field. We assume that the sender and receiver share a\ntwo-mode Gaussian state and we identify optimum local Gaussian operations that\nmaximize the teleportation fidelity. We consider fidelity of teleportation of\npure Gaussian states and we also introduce fidelity of the teleportation\ntransformation. We show on an explicit example that in some cases the optimum\nlocal operation is not a simple unitary symplectic transformation but some more\ngeneral completely positive map.",
