A Universal Fault-Tolerant Quantum Computing Architecture with Globally Driven Atom Arrays
Abstract
Scalable quantum computation requires reconciling programmability with simple, high-fidelity control. Here, we propose a universal fault-tolerant architecture using globally driven dual-species atom arrays. In a hybrid neutral-atom system, interspecies Rydberg interactions enable qubit addressability without locally addressed quantum gates. We construct a universal native instruction set, Global Rydberg Atom Instruction Language (GRAIL), and show that crosstalk errors can be suppressed to the 10−4 level. We compile surface-code error correction and magic state cultivation into GRAIL, and parallelize the compilation to suppress crosstalk. Under a hardware-inferred circuit-level noise model, we obtain an error-correction threshold of 1.43% for the resulting quantum memory and a logical error rate below 10−9 for magic states cultivated at an experimentally accessible Rydberg Rabi frequency. By replacing local gate addressing with atom-mediated selectivity, this architecture removes the associated calibration requirements, offering a route to simpler control for large-scale fault-tolerant neutral-atom computation.
