    "abstract": "We show that the recently proposed scheme of teleportation of continuous\nvariables [S.L. Braunstein and H.J. Kimble, Phys. Rev. Lett. 80, 869 (1998)]\ncan be improved by a conditional measurement in the preparation of the\nentangled state shared by the sender and the recipient. The conditional\nmeasurement subtracts photons from the original entangled two-mode squeezed\nvacuum, by transmitting each mode through a low-reflectivity beam splitter and\nperforming a joint photon-number measurement on the reflected beams. In this\nway the degree of entanglement of the shared state is increased and so is the\nfidelity of the teleported state.",
