Preparation of W, GHZ, and two-qutrit states using bimodal cavities

Abstract

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 multiatom 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 $\Lambda$ configuration simultaneously interacting with a resonant two-mode cavity for this purpose. Our approach permits a variety of multiparticle extensions.
