离子阱量子信息处理面临的一个突出挑战是以可扩展的方式精确检测许多离子的状态。在表面陷阱的特定情况下，几何约束使得垂直于表面的成像吸引在多个位置处以最小串扰收集光。在这份报告中，我们描述了一个实验集成衍射光学元件（DOE的）与表面电极陷阱，通过在真空多模光纤连接。这里报道的正方形DOE均设计为立体角收集效率为3.58%;在包括所有损失的情况下，用单个Ca+离子测量的检测效率为0.388%（1.02%，不包括PMT损失）。DOE的存在对离子的稳定性影响最小，无论是在杂散电场的时间变化和运动加热速率。
One of the outstanding challenges for ion trap quantum information processing is to accurately detect the states of many ions in a scalable fashion. In the particular case of surface traps, geometric constraints make imaging perpendicular to the surface appealing for light collection at multiple locations with minimal cross-talk. In this report we describe an experiment integrating Diffractive Optic Elements (DOE's) with surface electrode traps, connected through in-vacuum multi-mode fibers. The square DOE's reported here were all designed with solid angle collection efficiencies of 3.58%; with all losses included a detection efficiency of 0.388% (1.02% excluding the PMT loss) was measured with a single Ca+ ion. The presence of the DOE had minimal effect on the stability of the ion, both in temporal variation of stray electric fields and in motional heating rates.
