We report on the realization of a large-scale quantum-processing architecturesurpassing the tier of 1000 atomic qubits. By tiling multiplemicrolens-generated tweezer arrays, each operated by an independent lasersource, we can eliminate laser-power limitations in the number of allocatablequbits. Already with two separate arrays, we implement combined 2Dconfigurations with a mean number of 1167(46) single-atom quantum systems. Thetransfer of atoms between the two arrays is achieved with high efficiency.Thus, supercharging one array designated as quantum processing unit with atomsfrom the secondary array significantly increases the number of qubits and theinitial filling fraction. This drastically enlarges attainable qubit clustersizes and success probabilities allowing us to demonstrate the defect-freeassembly of clusters of up to 441 qubits with persistent stabilization atnear-unity filling fraction over tens of detection cycles. The presented methodsubstantiates neutral atom quantum information science by facilitatingconfigurable geometries of highly scalable quantum registers with immediateapplication in Rydberg-state mediated quantum simulation, fault-tolerantuniversal quantum computation, quantum sensing, and quantum metrology.
