Teleportation of an atomic ensemble quantum state
Aurelien Dantan, Nicolas Treps, Alberto Bramati, Michel Pinard
Abstract
We propose a protocol to achieve high fidelity quantum state teleportation of a macroscopic atomic ensemble using a pair of quantum-correlated atomic ensembles. We show how to prepare this pair of ensembles using quasiperfect quantum state transfer processes between light and atoms. Our protocol relies on optical joint measurements of the atomic ensemble states and magnetic feedback reconstruction.
