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.
