论文摘要
互相关信号是从散落在自由空间的离子结构中的荧光光子中记录的。信号的分析允许明确揭示空间频率，因此距离以及离子的空间比对。 For the case of two ions we obtain from the cross-correlations a spatial frequency $f_\text{spatial}=1490 \pm 2_{stat.}\pm 8_{syst.}\,\text{rad}^{-1}$, where the statistical uncertainty improves with the integrated number of correlation events as $ n^{ - 0.51 \ pm0.06} $。我们独立地确定空间频率为$ 1494 \ pm 11 \，\ text {rad}^{ - 1} $，证明了出色的协议。将我们的方法扩展到三个离子的情况下，我们证明了它在无法区分的光子发射器的二维阵列中的功能，作为模型系统，可在直接成像技术失败的情况下产生结构信息。
Cross-correlation signals are recorded from fluorescence photons scattered in free space off a trapped ion structure. The analysis of the signal allows for unambiguously revealing the spatial frequency, thus the distance, as well as the spatial alignment of the ions. For the case of two ions we obtain from the cross-correlations a spatial frequency $f_\text{spatial}=1490 \pm 2_{stat.}\pm 8_{syst.}\,\text{rad}^{-1}$, where the statistical uncertainty improves with the integrated number of correlation events as $N^{-0.51\pm0.06}$. We independently determine the spatial frequency to be $1494\pm 11\,\text{rad}^{-1}$, proving excellent agreement. Expanding our method to the case of three ions, we demonstrate its functionality for two-dimensional arrays of emitters of indistinguishable photons, serving as a model system to yield structural information where direct imaging techniques fail.
