| Abstract: | Realizing the teleportation of superposition of even and odd coherent states of cavity field is of great importance in quantum information.A feasible scheme is proposed to probabilistically teleport superposition of even and odd coherent states of the cavity field by the interaction of V-type three-level atom with the cavity-field of large amplitude under a far-off resonant condition.In this scheme,by performing Bell state measurement,the superposition of even and odd coherent states of the cavity field can be successfully achieved with a total probability of 0.25. |
