  We suggest a nanoelectromechanical setup and corresponding time-protocol for
controlling parameters in order to demonstrate nanomechanical manipulation of
superconducting charge-qubit quantum network. We illustrate it on an example
reflecting important task for quantum information processing - transmission of
quantum information between two charge-qubits facilitated by nanomechanics. The
setup is based on terminals utilizing the AC Josephson effect between bias
voltage-controlled bulk superconductors and mechanically vibrating mesoscopic
superconducting grain in the regime of the Cooper pair box, controlled by the
gate voltage. The described manipulation of quantum network is achieved by
transduction of quantum information between charge-qubits and intentionally
built nanomechanical coherent states, which facilitate its transmission between
qubits. This performance is achieved using quantum entanglement between
electrical and mechanical states.
