Preparation of Two-Qutrit Entangled State in Cavity QED

Abstract

We propose a scheme to generate a 3×3-dimensional maximally entangled state of two particles. Two three-level atoms interact with a strongly detuned cavity so that the cavity is only virtually excited and efficient decoherence time of the cavity is greatly prolonged. Compared to other protocols, this protocol is simpler and has a higher fidelity.
