Arrays of neutral atoms in optical tweezers have enabled a wide range of advances in quantum science. However, the spatial region in which tweezers can be generated is limited by design constraints of high-NA microscope objectives. Many applications would benefit from the ability to position optical tweezers over a much larger area. For example, it may be beneficial to transport atom arrays in and out of a microwave or optical cavity. Long-distance-transportable arrays may also find application in precision measurements probing the effects of gravity or other delocalized fields. Finally, highly-parallelized transport of atom array between computational modules presents a new paradigm for modular quantum computing. By placing a microscope objective on an air-bearing linear motion stage, we demonstrate the ability to translate large tweezer arrays over 200 mm. A novel beam-folding technique preserves the optical path length between the objective and the preceding lens during this translation. We will present the ability to move the array with acceleration 2g and velocity 1 m/s with a repeatability on the sub-100-nm scale. Finally, we will present our vision to realize a large-scale modular quantum computer with this architecture.
