Abstract

A scheme is proposed to implement quantum state transfer between two distant atoms through sending the atoms across two distant cavities connected via an optical fiber. The field state, which preserves the information of the first atom, is transmitted from one cavity to the other along the fiber. After the field interacts with the second atom for a defined time, the state transfer can be accomplished with unit efficiency. The realization of this scheme is within current experiment technology.
