    "abstract": "In standard coherent state teleportation with shared two-mode squeezed vacuum\n(TMSV) state there is a trade-off between the teleportation fidelity and the\nfidelity of estimation of the teleported state from results of the Bell\nmeasurement. Within the class of Gaussian operations this trade-off is optimal,\ni.e. there is not a Gaussian operation which would give for a given output\nfidelity a larger estimation fidelity. We show that this trade-off can be\nimproved by up to 2.77% if we use a suitable non-Gaussian operation. This\noperation can be implemented by the standard teleportation protocol in which\nthe shared TMSV state is replaced with a suitable non-Gaussian entangled state.\nWe also demonstrate that this operation can be used to enhance the transmission\nfidelity of a certain noisy channel.",
