Neutral-atom arrays have emerged as a versatile platform toward scalable quantum computation and optimization. In this paper, we present demonstrations of solving maximum-weighted independent-set problems on Rydberg-atom array using annealing with local light shifts. We verify the ability to prepare weighted graphs in one-dimensional (1D) two-dimensional (2D) arrays, including embedding five-vertex nonunit-disk graph nine physical qubits demonstration simple crossing gadget. find common...
Neutral atoms are a promising platform for scalable quantum computing, however, prior demonstration of high fidelity gates or low-loss readout methods have employed restricted numbers qubits. Using randomized benchmarking microwave-driven single-qubit gates, we demonstrate average gate errors 7(2)×10^{-5} on 225 site atom array using conventional, destructive readout. We further factor 1.7 suppression the primary measurement via low-loss, nondestructive, and state-selective 49 sites while...
