金刚石中的氮-空位(NV)色心受到越来越多研究学者的青睐, 这种色心在量子信息应用领域具有非常好的自旋和光学性能。为了更好地研究这些性能, 精确探测金刚石中NV色心轴向信息非常必要。介绍了一种利用多束偏振光准确测量两个相邻NV色心组合包含的轴向信息的新方法, 该方法可以探测出在四种可能轴向中, 两个高度重合色心的轴向分布信息。

Negatively charged nitrogen-vacancy (NV) centers in diamond are attractive candidates because of their excellent spin and optical characteristics for quantum information and metrology. To research these characteristics, precise orientation of the NV axis in the lattice is essential. The information of axis orientation of two adjacent NV centers in diamond can be efficiently measured through multi linearly polarized beams, and the method can measure axial information of two adjacent NV centers from four possible axes.
