标题： Super-resolution optical trapping of multiple cold atoms

摘要： 光学镊子阵列是中性原子模拟和数字量子处理器的核心。 然而，为了防止干扰引起的陷阱畸变，阱间的距离通常远大于镊子的尺寸，从而限制了阱的密度。 在这里，我们报告在四个超分辨镊子中实现单原子捕获，这意味着它们之间的距离低于斯帕罗衍射极限。 光学图案是通过超振荡现象生成的，从而产生亚波长陷阱，并能完全控制陷阱的相对相位。 我们研究了两种相对相位，它们会阻碍或允许原子的跃迁和重新排列。 我们设想，超振荡光结构将弥合由镊子阵列产生的远距离陷阱与由光晶格形成的近距离陷阱之间的差距。 显示英文摘要

摘要： Arrays of optical tweezers form the backbone of neutral atoms analog and digital quantum processors. However, the inter-trap distance remains generally much larger than the size of the tweezers to avoid interference-induced trap distortions, limiting the trap density. Here, we report single-atom trapping in four super-resolved tweezers, meaning with a separation below the Sparrow diffraction limit. The optical pattern is generated using superoscillatory phenomenon leading to subwavelength traps with full control of the trap relative phases. We investigate two sets of relative phases that impede or allow the hopping and the reshuffling of atoms. We envision that superoscillatory light structuring will bridge the gap between large-distance traps generated by tweezer arrays and short-distance traps formed with optical lattices.
