As a potential candidate for quantum computation and metrology, the nitrogen vacancy (NV) center in diamond faced both challenge and opportunity resulted from charge state conversion.Using the optimized optical manipulation of charge state, we developed the charge state depletion (CSD) microscopy with sub-diffraction resolution.Subsequently, the electron spin states dynamics of adjacent NV centers were selectively detected with the CSD.Experimental results demonstrated that CSD can improve the spatial resolution in the control of NV centers for nanoscale sensing and quantum information.

提高光学系统成像分辨率无论对于经典光学还是量子光学而言都是一个重要课题[1].在衍射受限成像系统中,分辨极限定义为物面两点间的最小可分辨距离,即瑞利极限,表达式为δx=0.61λ/NA,其中λ为光波波长,NA是数值孔径.Kim组验证散斑自关联二阶成像可以突破透镜成像系统的瑞利极限,实验数据表明分辨极限为瑞利极限之下0.75,此时散斑一阶成像不能分辨物体[2].
