We propose a scheme to achieve switchable coupling between nitrogen-vacancy (N-V) center in diamond and superconducting charge qubit by a quantized nanomechanical resonator (NAMR) as a data bus. This procotol can be used to transfer the quantum state from charge qubit to N-V center. Owing to the N-V center has relatively long decoherence time, the information can be stable stored in it. Finally, we discuss the experimental feasibility of our scheme.
