Transferring atomic entangled states with a nonresonant atom-field interaction

A scheme is proposed for transferring two-atom entangled state and W state.It is based on the simultaneous nonresonant interaction of two atoms with a single-mode cavity field.During the transferring process,the atoms do not transfer quantum information with the cavity.The cavity is only virtually excited and thus the requirement on the quality factor of the cavity is greatly loosened.Atomic entangled state can be directly transferred to the atoms of receiver without performing any measurement.The successful probability is 100 percent.
