论文摘要
我们报告了300多个单一$^{87} $ rb原子的大型组装阵列的实现，在低温环境中以$ \ sim4 $ 〜k捕获的光学镊子被困在光学镊子中。对于具有$ n _ {\ rm a} = 324 $原子的数组，汇编过程在实现的$ \ sim37 \％$中导致无缺陷数组。为了达到这一高组装效率，我们基于对陷阱中装载的原子的荧光时间跟踪的分析，使用每个光学镊子的闭环优化阵列内陷阱的加载概率。
We report on the realization of large assembled arrays of more than 300 single $^{87}$Rb atoms trapped in optical tweezers in a cryogenic environment at $\sim4$~K. For arrays with $N_{\rm a}=324$ atoms, the assembly process results in defect-free arrays in $\sim37\%$ of the realizations. To achieve this high assembling efficiency, we equalize the loading probability of the traps within the array using a closed-loop optimization of the power of each optical tweezers, based on the analysis of the fluorescence time-traces of atoms loaded in the traps.
