Generation of Multi-atom Entanglemen

Generation of Multi-atom Entanglement of Greenberger-Horne-Zeilinger and W States in Cavity QED

A method to prepare multi-particle entanglement of Greenberger-Horne-Zeilinger-type and W-type is proposed through the interaction between the cavity and many atoms simultaneously . After suitable interaction, the selected measurements on the cavity field can create the entangled atomic states. These entangled states can be useful for quantum information manipulation and fundamental study of quantum theory. These states that violate the Bell's inequality are proven.
