  We show the quantum state transfer technique in two-color photoassociation
(PA) of a Bose-Einstein condensate, where a quantized field is used to couple
the free-bound transition from atom state to excited molecular state. Under the
weak excitation condition, we find that quantum states of the quantized field
can be transferred to the created molecular condensate. The feasibility of this
technique is confirmed by considering the atomic and molecular decays
discovered in the current PA experiments. The present results allow us to
manipulate quantum states of molecules in the photoassociation of a
Bose-Einstein condensate.
