We present a scheme to generate a maximally entangled state of two three-level atoms with a nonresonant cavity by cavity-assisted collisions. Since the cavity field is only virtually excited, no quantum information will be transferred from the atoms to the cavity.
We propose a scheme to generate maximally entangled states (MESs) of multiple three-level atoms in microwave cavity QED based on the resonant atom-cavity interaction. In the scheme, multiple three-level atoms initially in their ground states are sequently sent through two suitably prepared cavities. After a process of appropriate atom-cavity interaction, a subsequent measurement on the second cavity field projects the atoms onto the MESs. The practical feasibility of this method is also discussed.
