摘要:

我们报告了一个低损耗,宽带光学天线,使高度定向输出从一个相干的单自旋在固态。该器件是介电天线的第一个固态实现,是为金刚石中的单个氮空位(NV)电子自旋而设计的。我们证明方向性接近10。光子结构保持了单晶金刚石的高自旋相干性(T2> 100 μ s)。单光子计数率接近MHz,促进有效的自旋读出。因此,我们展示了量子应用的关键技术,如高灵敏度磁力测量和长距离自旋纠缠。

英文摘要:

We report the creation of a low-loss, broadband optical antenna giving highly directed output from a coherent single spin in the solid-state. The device, the first solid-state realization of a dielectric antenna, is engineered for individual nitrogen vacancy (NV) electronic spins in diamond. We demonstrate a directionality close to 10. The photonic structure preserves the high spin coherence of single crystal diamond (T2>100us). The single photon count rate approaches a MHz facilitating efficient spin readout. We thus demonstrate a key enabling technology for quantum applications such as high-sensitivity magnetometry and long-distance spin entanglement.
