Large-scale multilayer architecture of single-atom arrays with individual addressability

We report on the realization of a novel platform for the creation of large-scale 3D multilayer configurations of planar arrays of individual neutral atoms: a microlens-generated Talbot optical lattice. We demonstrate the trapping and imaging of rubidium atoms in integer and fractional Talbot planes and realize the in-plane assembly of defect-free atom arrays. We present interleaved lattices with dynamic position control and parallelized sub-lattice addressing of spin states. The single beam illumination of a microlens array constitutes a structurally robust and wavelength-universal method for the realization of 3D atomic arrays with favourable scaling properties due to the inherent self-imaging of the focal array. Geometry and trap size are configurable in the micrometer regime with immediate applications in quantum science and technology.
