摘要：
我们报告了一种新平台的实现，该平台用于创建大规模三维多层构型的中性原子量子比特平面阵列：一种由微透镜生成的Talbot光镊晶格，它将二维光镊阵列扩展到第三维度，且无需额外成本。我们演示了在整数和分数Talbot平面上对铷原子的捕获和成像，以及在不同层中组装无缺陷原子阵列。微透镜阵列的Talbot自成像效应构成了一种结构稳健且波长普适的方法，用于实现具有有利缩放特性的三维原子阵列。每个二维层拥有超过750个量子比特位点，这些缩放特性意味着在我们当前的实现中，三维空间内已可访问10000个量子比特位点。陷阱拓扑和功能可在微米尺度内配置。我们利用这一点生成具有动态位置控制和自旋态并行化子晶格寻址的交错晶格，以直接应用于量子科学与技术。
英文摘要：
We report on the realization of a novel platform for the creation of large-scale 3D multilayer configurations of planar arrays of individual neutral-atom qubits: a microlens-generated Talbot tweezer lattice that extends 2D tweezer arrays to the third dimension at no additional costs. We demonstrate the trapping and imaging of rubidium atoms in integer and fractional Talbot planes and the assembly of defect-free atom arrays in different layers. The Talbot self-imaging effect for microlens arrays constitutes a structurally robust and wavelength-universal method for the realization of 3D atom arrays with beneficial scaling properties. With more than 750 qubit sites per 2D layer, these scaling properties imply that 10000 qubit sites are already accessible in 3D in our current implementation. The trap topology and functionality are configurable in the micrometer regime. We use this to generate interleaved lattices with dynamic position control and parallelized sublattice addressing of spin states for immediate application in quantum science and technology.
