This article tackles a critical bottleneck in neutral‑atom quantum computers: the joint spatial‑temporal compilation problem that has limited circuit depth as systems scale. By decoupling geometry from timing and using a graph‑neural‑network predictor to preselect high‑parallelism layouts, ARGON achieves compilation times under ten seconds—orders of magnitude faster than prior methods—and thereby makes real‑time scheduling for large neutral‑atom arrays feasible. The work positions machine‑learning‑assisted compilers as essential infrastructure for the next generation of scalable quantum hardware, though experimental validation on actual devices will be needed to confirm the predicted fidelity gains.

Summary
Neutral atom quantum systems offer a promising pathway to large-scale quantum computing due to high qubit uniformity and flexible connectivity. To exploit this architecture, compilers must coordinate dynamic atom transport alongside highly parallel entangling gates. As circuits scale, the interplay between these operations becomes a system bottleneck, introducing denser logical interactions and longer temporal dependencies. Compilers must simultaneously satisfy rigid spatial constraints and complex movement schedules. Existing joint spatiotemporal compilation methods face an exponentially expanding search space, incurring substantial overheads or compromising fidelity as circuit size grows. In this work, we propose ARGON, a scalable compilation framework that introduces a spatiotemporal decoupling paradigm for neutral atom processors. Our key novelty is offloading static geometric conflict resolution to an offline phase, precomputing a library of hardware-certified, high-parallelism spatial layouts. To guide temporal routing, we deploy a Graph Neural Network (GNN) predictor to evaluate candidate layouts against deep temporal horizons, proactively evading downstream kinematic bottlenecks. Finally, a heuristic router translates the selected sequence into collision-free physical transport. Evaluations show ARGON completes compilation in under 10 seconds, delivering up to a >10^4x and 600x average speedup over state-of-the-art baselines. ARGON also minimizes routing decoherence and reduces Rydberg stages, improving execution fidelity by up to 10^2x on dense circuits.
