摘要

Using a system of cavity quantum electrodynamics (QED) we present two schemes for multipartite entanglement generation.In the first scheme,a three-level atom is interacting with three cavities successively.In the second one,two three-level atoms are interacted with a coherent optical cavity.These protocols allow us to generate the six classes of tripartite entanglement (GHZ,W,A-B-C,AB-C,C-AB,and B-AC class states) by controling the interaction time between atoms and cavities.Moreover,they allow us to generate entanglement between the cavity fields degrees of freedom (from the first scheme),and a mixed entanglement between the cavity field degrees of freedom and the atomic degrees of freedom.
