Entanglement swapping using continuous variables

Quantum Physics 2009-01-23 v1

Abstract

We investigate the efficacy with which entanglement can be teleported using a continuous measurement scheme. We show that by using the correct gain for the classical channel the degree of violation of locality that can be demonstrated (using a CH type inequality) is {\it not} a function of the level of entanglement squeezing used in the teleportation. This is possible because a gain condition can always be choosen such that passage through the teleporter is equivalent to pure attenuation of the input field.
