Out of the consideration of scalability and convenience, all-electrical control of quantum dynamics in quantum information processing is highly desirable. Here we describe a scheme of all-electrical control of the quantum interface between optical qubits and charge qubits mediated by a nanoscale mechanical resonator. This quantum interface can accomplish many key tasks of a quantum network, such as transferring, swapping, and entangling qubits between distant nodes of a quantum network. Numerical simulations show that high fidelity operations on this quantum interface under realistic experimental conditions are reachable.
