利用室温静磁表面自旋波（MSSWs）介导天线微波场与金刚石中氮空位（NV）中心自旋之间的相互作用。我们发现这种输运跨越超过3毫米的距离，这是MSSW鲁棒性和大扩散长度的表现。使用NV自旋作为局部传感器，我们发现MSSW共振耦合，并且NV自旋振幅随微波功率线性增长，这表明该方法可以扩展到将来自相邻自旋量子比特的信号放大几个数量级。(C) 2017 .日本应用物理学会
We make use of room-temperature magnetostatic surface spin waves (MSSWs) to mediate the interaction between the microwave field from an antenna and the spin of nitrogen-vacancy (NV) centers in diamond. We show that this transport spans distances exceeding 3 mm, a manifestation of the MSSW robustness and large diffusion length. Using the NV spins as a local sensor, we find that the MSSW couples resonantly, and the NV spins amplitude grow linearly with the applied microwave power, suggesting that this approach could be extended to amplify the signal from neighboring spin qubits by several orders of magnitude.
