Abstract
We show that the fidelity of teleportation of continuous quantum variables can be improved by conditional photon-number measurement of the entangled s tate. Further, we propose a teleportation scheme based on photon counting o n the output fields of a squeezer that combines the mode whose quantum stat e is desired to be teleported and one mode of the two-mode squeezed vacuum playing the role of the entangled state.
