Teleportation of an unknown odd-even-coherent state via the Raman interaction of Ⅴ-type three-level-atom and coherent cavity field

The Raman interaction of degenerate Ⅴ-type three-level atom and coherent cavity-field are described and the interaction formulae between atoms of excited states and coherent light cavity fields are obtained.The greatest entangled state is prepared by utilizing the interaction of measurement atom and coherent light cavity field，and the atom is injected in the cavity field.With the revolution of the Bell bases constructed by the atom and the cavity-mode，and selective measurement on the atomic states，the probable quantum states of measurement cavity-field are obtained after the interaction.Then，by means of joint measurement on the cavity-field and the atom，and an unitary transformation on the measurement quantum states，the measurement quantum states of the odd-even coherent field are prepared into as the same as the initial quantum state of the cavity-field to be measured.It follows that the teleportation of an unknown odd-even coherent cavity-field is realized.
