| Abstract: | In this paper, we study quantum teleportation of atomic states via ahybrid entangled state (HES) involving an atom and a cavity field.And we investigate how to implement controlled phase (CP) gatesbetween atomic internal states and coherent states of cavity field.We also discuss the methods of distinguishing coherent states|±α〉in a cavity. Finally, a brief discussion aboutthe feasibility of this scheme in experiment is presented. |
