When QuEra made Aquila available on Amazon Braket in late 2023, industry observers questioned whether analog neutral-atom hardware had a path to broad adoption. The programming model was unfamiliar — no circuit gates, instead a Hamiltonian evolution spec — and the lack of single-qubit addressability seemed limiting. Three years later, those concerns look premature.
What the Data Shows
QuEra disclosed that Aquila has processed over 2 million cloud jobs since launch, representing the most cloud executions of any neutral-atom system. The user base spans 47 countries, primarily university research groups (68%) and national laboratories (22%).
Published research using Aquila includes: - Quantum spin liquid simulation: A Harvard-led team used Aquila to simulate the ground state of a ruby lattice Hamiltonian at 219 atoms — the largest quantum simulation of a frustrated magnetic system - Optimization benchmarking: Multiple groups ran QUBMIS (maximum independent set) problems, confirming Aquila's native advantage for Rydberg-blockade-compatible graph problems - Quantum phase transitions: Studies of confinement/deconfinement transitions in Z₂ lattice gauge theories at scales unreachable by classical tensor network methods
Platform Limitations That Remain
Aquila's analog mode lacks single-qubit control — all atoms receive the same drive pulse, and spatial addressing is limited. This rules out arbitrary gate sequences. The platform excels at problems naturally described by 2D Rydberg Hamiltonians; users trying to force arbitrary optimization problems into this model face significant formulation overhead.
Atom loading efficiency is approximately 97% per site, meaning a 256-site array has a small probability of loading with missing atoms. Software compensation handles most cases, but it adds a layer of stochasticity researchers must account for.
What's Coming
QuEra is developing a gate-based mode for the successor to Aquila (internal codename Helios) with individual qubit addressing via local laser beams. QuEra CEO Nate Gemelke confirmed at IEEE Quantum Week 2025 that gate-based Aquila access is targeted for 2026. If delivered, this would make QuEra's platform competitive with trapped-ion and superconducting systems for gate-based workloads while retaining the large-scale analog simulation capability.
