论文摘要
基于钻石的磁力计中氮胶菌（NV）颜色中心的敏感性很大程度上取决于与测量相关的NV中心的数量。不幸的是，如果氮含量超过一定的阈值水平（大约$ {10^{17}} {\ rm {c}} {\ rm {\ rm {m}^{ - 3}} $），则NV中心浓度的浓度越来越导致其去度和相干时间的减少。在这里，我们证明，可以通过在阈值音乐会附近进行后处理程序来有效地补偿这种增加的分类，从而扩展了在具有天然碳含量的钻石中最大可能的分解时间的NV中心的可能有用浓度。
The sensitivity of the nitrogen-vacancy (NV) color centers in diamond-based magnetometers strongly depends on the number of NV centers involved in the measurement. Unfortunately, an increasing concentration of NV centers leads to decreases of their dephasing and coherence time if the nitrogen content exceeds a certain threshold level (approximately ${10^{17}}{\rm{ c}}{\rm{m}^{ - 3}}$). Here, we demonstrate that this increased dephasing can be efficiently compensated by postprocessing procedures in the vicinity of the threshold concertation, thus extending possible useful concentrations on NV centers with the maximum possible decoherence time in diamonds with a natural carbon content.
