我们提出了一个方案的任意光学接口介导的纳米机械振荡器之间的飞行量子比特和光学非有源固态量子比特的控制。这种量子接口为量子网络的许多关键功能奠定了基础，例如在量子网络的远程节点之间传输，交换和纠缠量子位。量子接口操作的数值模拟显示了在现实实验条件下的高精度和鲁棒的公差。与已有方案[K. Stannigel等人，物理修订信函105，220501（2010）]，其可显著增加高保真度的状态转移操作的速度。
We present a scheme of control for the arbitrary optical interface mediated by a nanoscale mechanical oscillator between flying qubits and optical nonactive solid-state qubits. This quantum interface lays the foundation for many key functions of a quantum network, such as transferring, swapping, and entangling qubits between distant nodes of a quantum network. Numerical simulations of the quantum interface operations show high fidelities and robust tolerance under realistic experimental conditions. Compared with a previous scheme [K. Stannigel et al., Phys. Rev. Lett. 105, 220501 (2010)], it may significantly increase the speed of state transfer operation of high fidelity.
