Abstract
The teleportation of the signal beam of a parametric amplifier is considere d, and its entanglement with the idler beam before and after the teleportat ion process is computed. A criterion based on homodyne measurements is prop osed to discount purely classical effects, and it is suggested that the pre servation of the Einstein-Podolsky-Rosen correlations during teleportation may be verified experimentally.
