This research introduces Piqasso, a compiler specifically designed to leverage the three-dimensional architecture of neutral-atom quantum computers rather than treating them as flat planes. By utilizing vertical hops and layered scheduling, it significantly reduces atom transport distances and execution times compared to existing planar compilers. The work represents a critical advancement in hardware-aware compilation that directly addresses scaling challenges for 3D tweezer arrays.
Compiler Framework for 3D Neutral-Atom Quantum Computers
arXiv:2608.01316v1 Announce Type: new Abstract: Neutral-atom quantum computers can now arrange atoms in three-dimensional tweezer arrays, yet every existing compiler assumes a flat geometry. We present Piqasso, a compiler that exploits the vertical axis by stacking storage, entanglement, and readout into distinct layers. Its pipeline pairs an analytical placement respecting axial-clearance optics with a router that brings gate partners together via short vertical hops---bypassing in-plane crossing conflicts through out-of-plane detours---and a multi-AOD scheduler that parallelizes transport across focal planes. On 34 circuits, Piqasso reduces atom transport distance by 2.1$\times$ over a state-of-the-art planar compiler, yielding up to 7.3$\times$ faster execution, 2.2$\times$ higher movement fidelity, and 1.8$\times$ fewer serialized transport rounds, with all gains widening at scale.
