摘要：

We propose an experimentally feasible scheme for implementing a two-ion swap gate in the context of the ion-trap system. In this scheme, we drive the ion with one laser beam and we map the states of one ion and the emotional mode to each other. The scheme is based on resonant side band excitation, and thus it may be realized with current ion-trap techniques.
