A scheme is proposed for the teleportation of a unknown superposition-state of coherent-states via Raman interaction of a degenerate V-type three-level atom with cavity-field.

A method is presented for generating superpositions of coherent states of a cavity field via the atom - cavity-field Raman interaction. After an atom has interacted with a cavity field, initially in a coherent state, it is detected through the Raman coupling. Then the cavity field collapses into a Schrödinger cat state.

A scheme is reported for the teleportation of entangled coherent states through the degenerate Raman interaction. The scheme uses an entangled state of an atom and two coherent states as a quantum channel. It makes full use of coherent cavity fields. Furthermore, it does not need any classical field to transform the atom states.
