Probabilistic remote preparation of a three-atom Greenberger-Horne- Zeilinger class state via cavity quantum electrodynamics

We present two schemes for remotely preparing a three-atom Greenberger-HorneZeilinger class state via entanglement swapping in cavity quantum electrodynamics. We show that each of our schemes can be achieved probabilistically by means of separate atomic measurements with the choice of an appropriate atom-cavity field interaction time.
