We describe a new scheme to interconvert stationary and photonic qubits which is based on indirect qubit-light interactions mediated by a mechanical resonator. This approach does not rely on the specific optical response of the qubit and thereby enables optical quantum interfaces for a wide range of solid state spin and charge based systems. We discuss the implementation of state transfer protocols between distant nodes of a quantum network and show that high transfer fidelities can be achieved under realistic experimental conditions.
我们描述了一种新的方案，用于通过机械谐振器介导的间接量子比特-光相互作用来转换静止和光子量子比特。这种方法不依赖于量子比特的特定光学响应，从而为广泛的基于固态自旋和电荷的系统实现了光学量子接口。我们讨论了在量子网络的远程节点之间实现状态传输协议的实现，并表明在实际实验条件下可以实现高传输保真度。
