我们报告的单氮空位（NV）中心的耦合，以纳米金刚石荧光的实时观察下的纳米纤维上的单金刚石纳米晶体的操纵，以双锥纤维锥形纳米纤维。单NV中心的自旋相关荧光通过荧光显微镜有效地检测。我们展示了使用外部磁场对电子基态的自旋子能级结构的控制，并且清楚地观察到m（S）=垂直条+/-1>的频率微调。这一观察结果表明，实现光纤集成量子级联系统的可能性，该系统可用于各种量子信息设备，包括推挽量子存储器和量子门。
We report on the coupling of single nitrogen vacancy (NV) centers to ultrathin fiber-taper nanofibers by the manipulation of single diamond nanocrystals on the nanofibers under real-time observation of nanodiamond fluorescence. Spin-dependent fluorescence of the single NV centers is efficiently detected through the nanofiber. We show control of the spin sub-level structure of the electronic ground state using an external magnetic field and clearly observe a frequency fine tuning of m(S) = vertical bar +/- 1 >. This observation demonstrates a possibility of realizing fiber-integrated quantum lambda-systems, which can be used for various quantum information devices including push-pull quantum memory and quantum gates.
