  • 摘要:

    针对金刚石内13C核自旋的逐个定位,提出了一种非均匀分布周期内对称的动态解耦序列--可调动态解耦(APDD)序列。针对该序列,进行了理论推导和仿真分析;并就13C核自旋定位精度指标,与目前金刚石内原子量子态操控使用最为广泛的CPMG(Carr-Purcell-Meiboom-Gill)脉冲序列和XY4序列进行了比较。结果表明,相比于CPMG序列与XY4序列,APDD序列可将单个13C核自旋的定位精度提高6.27倍。进一步研究表明,在单个周期内比值τ1/τ介于0.51~0.58范围为APDD序列核子定位最优工作条件。因此,APDD序列能被用于控制毗邻金刚石中NV-色心的核自旋,并且在量子信息和量子探测器领域有着重要的应用。
