A scheme for the generation of a three-dimensional N-atom GHZ state is proposed by combining some two-qubit swap operations and single-qubit rotation operations. The swap operation can easily be achieved by the large-detuned coupling of two distant atoms to two optical-fiber-connected cavities, respectively driven by two classical fields, and the single-bit rotation operation can be obtained by the interaction of an atom with a classical field. During the generation processes, atomic spontaneous emission and cavity decay are negligible. The scheme is realizable in experiments with current cavity quantum electrodynamics techniques.
