Scheme for the preparation of multiparticle entanglement in cavity QED

Here we present a quantum electrodynamics model involving a large-detuned single-mode cavity field and n identical two-level atoms. One of its applications for the generation of multiparticle entangled states of various kinds (Greenberger-Horne-Zeilinger states and different class of so-called W states) is analyzed. The theoretical prediction for the model of n=2 is made that is consistent with the experimental result by considering the possible three-atom collisions.
