What it does. Where it fits.
Neutral-atom gate-model quantum computing
Who should look closer
Teams investigating encoded circuits, small materials models and neutral-atom software workflows.
QubitWire’s editorial assessment of practical fit.Cloud and national testbed
CUDA-Q documents Sqale QPU access through a Superstaq account. Select a physical QPU explicitly; the default target is a simulator. NQCC access is governed by its testbed program.
Check the current access route ↗What has been demonstrated
A peer-reviewed study reports a small Anderson-model experiment with encoded qubits and reduced error after postselection. It explicitly identifies this materials application as non-fault-tolerant.
What remains unresolved
Postselected error detection does not establish general fault tolerance or commercial advantage. Testbed installation is distinct from repeated external application outcomes.
The next question to watch
Can repeated error-correction cycles and independently reported application trials extend performance beyond postselected demonstrations?
A research question, not a promised milestone.QubitWire coverage

Sources & evidence
- Fault-tolerant operation and materials science with neutral atom logical qubits ↗Organization-originated source · 5 Dec 2025
Infleqtion and collaborators report postselected error-detection experiments and a small Anderson-model ground-state demonstration. The materials application is explicitly non-fault-tolerant; this is not repeated active error correction.
- Infleqtion delivers operational 100-qubit system at the NQCC ↗Organization-originated source · 16 Mar 2026
Announces a 100-physical-qubit Sqale system at the NQCC, with the milestone reached in December 2025. Logical-qubit expansion goals are prospective.
- Quantum computing testbeds — NQCC ↗External source (may be a collaborator) · Publication date not stated
The host laboratory identifies Infleqtion’s SQALE neutral-atom testbed. Its related-news link to the 100-qubit announcement is not a separate performance evaluation.
- Neutral Atom — NVIDIA CUDA-Q documentation ↗Organization-originated source · Publication date not stated
Documents account-based Superstaq access and distinct simulator, dry-run and Sqale physical-QPU targets from CUDA-Q. Selecting the default backend runs a simulator.
- NVIDIA CUDA-Q runs logical-qubit application on Infleqtion QPU ↗Organization-originated source · 10 Dec 2024
The integration partner describes simulation followed by physical Sqale execution of the small materials experiment. This corroborates the workflow as partner evidence, not an independent replication.
