Optical tweezer arrays1,2 have transformed atomic and molecular physics, now forming the backone for a range of leading experiments in quantum computing3–8, simulation1,9–12, and metrolgy13–15. Typical experiments trap tens to hundreds of atomic qubits, and recently systems witharound one thousand atoms were realized without defining qubits or demonstrating coherent control16–18. However, scaling to thousands of atomic qubits with long coherence times, low-loss, andhigh-fidelity imaging is an outstanding challenge and critical for progress in quantum science, particularly towards quantum error correction19,20. Here, we experimentally realize an array of opticaltweezers trapping over 6,100 neutral atoms in around 12,000 sites, simultaneously surpassing stateof-the-art performance for several metrics that underpin the success of the platform. Specifically,while scaling to such a large number of atoms, we demonstrate a coherence time of 12.6(1) seconds, a record for hyperfine qubits in an optical tweezer array. We show room-temperature trappinglifetimes of ∼23 minutes, enabling record-high imaging survival of 99.98952(1)% with an imagingfidelity of over 99.99%. We present a plan for zone-based quantum computing5,21 and demonstratenecessary coherence-preserving qubit transport and pick-up/drop-off operations on large spatialscales, characterized through interleaved randomized benchmarking. Our results, along with recentdevelopments8,22–24, indicate that universal quantum computing and quantum error correction with
