Abstract

Some schemes for the entanglement generation of two and three distant cavity-fields and the distant transfer of a qubit atomic state and atomic entangled state are presented. The realization of entanglement swapping without measurement on Bell basis vectors and the operation of swap gate are proposed. These schemes are all based on Λ-type atoms interacting with bimodal under one-photon detuning and two-photon resonance. Finally, a discussion of experimental feasibility is given.
