| Abstract: | A scheme is proposed for quantum state transfer from the cavity field to the micromechanical cantilever and the realization of strong coupling. Our results show that a reliable high-fidelity quantum state transfer can be realized by modulating the system coefficients. Meanwhile, the strong coupling between the micromechanical cantilever and the CPW cavity has been generated via the NV center. Therefore, it is expected that our scheme could be utilized to realize large-scale quantum computation and quantum simulation. |
