A protocol is proposed to generate atomic entangled states and implement quantum information transfer in a cavity quantum electrodynamics system.It utilizes Raman transitions or stimulated Raman adiabatic passages between two systems to entangle the ground states of two three-state Λ-type atoms trapped in a single mode cavity.It does not need the measurements on cavity field nor atomic detection and can be implemented in a deterministic fashion.Since the present protocol is insensitive to both cavity decay and atomic spontaneous emission,it may have some interesting applications in quantum information processing.
