我们证明了C_{1}点群对称性的晶体场计算是可能的，并且这种计算可以以足够的准确度进行，对于基于稀土的量子信息应用具有实质性的实用性。特别地，我们对^{167}Er^{3+}：Y_{2}SiO_{5}中的一个C_{1}对称位进行了晶场拟合。计算同时包括高达20 000 cm^{-1}的位置选择性光谱数据、旋转塞曼数据以及由1.5 μm电信跃迁的高分辨率拉曼外差光谱确定的基态和激发态超精细结构。我们实现了优于50 MHz的协议指定的超精细过渡。这一分析的成功为系统地研究稀土离子在Y_{2}SiO_{5}中的相干性质、跃迁能量和强度提供了可能。
We show that crystal-field calculations for C_{1} point-group symmetry are possible, and that such calculations can be performed with sufficient accuracy to have substantial utility for rare-earth based quantum information applications. In particular, we perform crystal-field fitting for a C_{1}-symmetry site in ^{167}Er^{3+}:Y_{2}SiO_{5}. The calculation simultaneously includes site-selective spectroscopic data up to 20 000 cm^{-1}, rotational Zeeman data, and ground- and excited-state hyperfine structure determined from high-resolution Raman-heterodyne spectroscopy on the 1.5 μm telecom transition. We achieve an agreement of better than 50 MHz for assigned hyperfine transitions. The success of this analysis opens the possibility of systematically evaluating the coherence properties, as well as transition energies and intensities, of any rare-earth ion doped into Y_{2}SiO_{5}.
