Abstract

We present a scheme for quantum interfaces between nanomechanical and flying photon qubits. The quantum interface can accomplish many network operations such as generating or absorbing a single photon, distributing entanglement and transfer quantum states between nanomechanical and photon qubits. Based on this interface we can transfer quantum states and generate entanglement between two remote nanomechanical qubits. Numerical simulations show that near unity operation fidelities may be obtainable under realistic experimental circumstances.
