We show how one can prepare three-qubit entangled states like W-states, Greenberger-Horne-Zeilinger states as well as two-qutrit entangled states using the multi-atom two-mode entanglement. We propose a technique of preparing such a multi-particle entanglement using stimulated Raman adiabatic passage. We consider a collection of three-level atoms in Λ configuration simultaneously interacting with a resonant two-mode cavity for this purpose. Our approach permits a variety of multi-particle extensions.

A scheme is presented for preparing multi-atom entangled states based on the Raman atom-cavity-field interaction. After several degenerate Λ-type three-level atoms interact with an appropriately prepared single-mode cavity field through Raman coupling, a two-level atom, resonant with the cavity, is sent through the cavity and a Ramsey zone. The detection of the two-level atom leaves the Λ-type atoms in an entangled state.
