我们开发了一种结合$^{87}\text{Rb}$和$^{174}\text{Yb}$原子的双物种光镊阵列装置，该装置采用永久混合特怀曼-格林-菲佐干涉仪，可实现两个相对的数值孔径（NA）为0.6的物镜以及穿过系统的高NA光束的精密共对准。该技术可扩展到工作在高数值孔径、波长差异大的其他光镊平台。在此，我们展示了共对准光镊阵列中两种原子的同时囚禁和单原子分辨成像，其中$^{87}\text{Rb}$被限制在840nm处，$^{174}\text{Yb}$被限制在532nm处。该平台为混合量子寄存器操作提供了基础，包括中间电路测量以及不对称的种内和种间相互作用，极大地扩展了中性原子阵列的能力。
英文摘要
We have developed a dual-species optical tweezer array apparatus combining $^{87}\text{Rb}$ and $^{174}\text{Yb}$ atoms with a permanent hybrid Twyman-Green--Fizeau interferometer, which provides precision co-alignment of two opposing 0.6-numerical aperture (NA) objectives and the high NA beams that pass through the system. This technique is extensible to other tweezer platforms operating at high numerical aperture across widely-separated wavelengths. Here we present simultaneous trapping and single-site resolved imaging of both species in co-aligned tweezer arrays with $^{87}\text{Rb}$ confined at $840\ \rm{nm}$ and $^{174}\text{Yb}$ at $532\ \rm{nm}$. The platform provides a foundation for hybrid quantum register operation, including mid-circuit measurements and asymmetric intra- and inter-species interactions, greatly expanding the capabilities of neutral atom arrays.
