Conditional two mode squeezed vacuum teleportation

Quantum Physics 2007-05-23 v1

Abstract

We show, by making conditional measurements on the Einstein-Podolsky-Rosen (EPR) squeezed vacuum, that one can improve the efficacy of teleportation for both the position difference, momentum sum and number difference, phase sum continuous variable teleportation protocols. We investigate the relative abilities of the standard and conditional EPR states, and show that by conditioning we can improve the fidelity of teleportation of coherent states from below to above the Fˉ=2/3\bar{F} = 2/3 boundary.
