Infleqtion (NYSE: INFQ) has renewed its quantum software agreements with Sandia National Laboratories and Lawrence Berkeley National Laboratory and added a new partnership with Fermi National Accelerator Laboratory, extending its Superstaq platform across three Department of Energy research testbeds.

The partnerships center on Superstaq, Infleqtion's quantum software platform that manages how quantum instructions are prepared and executed across different hardware systems. For national laboratory teams, the pitch is straightforward: less time spent adapting software to each machine, more time on scientific discovery. Infleqtion has supported Sandia's Quantum Scientific Computing Open User Testbed (QSCOUT) and Berkeley Lab's Advanced Quantum Testbed since 2021, and the renewed agreements include software licensing plus close technical engagement aimed at keeping systems reliable as the testbeds scale in size and complexity.

The Fermilab collaboration is new territory. It extends Superstaq support to the Superconducting Quantum Materials and Systems Center (SQMS), which recently won renewal as one of DOE's National Quantum Information Science Research Centers. Infleqtion will work with Fermilab researchers to prepare and run quantum programs aligned with SQMS's research goals.

"Researchers at the national laboratories are working at the front edge of what is possible in quantum computing," said Pranav Gokhale, chief technology officer at Infleqtion. "These continued and expanded partnerships reflect the trust they place in Superstaq as one of the few quantum software platforms that works across different quantum computing technologies, helping researchers unlock meaningful performance improvements as they move from experiments toward real applications."

The lab-side commentary confirms sustained use rather than fresh adoption. "As part of ongoing work on the Advanced Quantum Testbed, Superstaq has provided software tools used to support quantum research and development," said Chris Spitzer, Quantum Research Program Manager at Lawrence Berkeley National Laboratory. "Continuing the collaboration supports researcher access to software tools needed for experiments on evolving quantum hardware."

Sandia's statement echoes the operational framing. "Superstaq has been an important part of the QSCOUT testbed since its early days," said Susan Clark, QSCOUT Principal Investigator at Sandia National Laboratories. "Continuing this collaboration supports our mission to provide researchers with reliable tools that enable experimentation, comparison, and advancement across emerging quantum computing approaches."

At Fermilab, the collaboration is still exploratory. "Through this collaboration with Infleqtion, SQMS is exploring pathways to pair advanced hardware with a flexible software platform," said Dr. Silvia Zorzetti, Principal Engineer at Fermi National Accelerator Laboratory. "The Superstaq platform supports the collaborative work underway at SQMS and helps our teams focus on translating foundational research into meaningful progress for the broader quantum ecosystem."

What the deals do and don't say

Neither the announcement nor the lab statements disclose contract values, licensing terms, or duration. The release offers no measured performance figures for Superstaq on any of the three testbeds — no gate-fidelity gains, no compilation benchmarks, no throughput numbers. Claims of "meaningful performance improvements" rest on Gokhale's characterization rather than published results, and the announcement itself was funded and issued by Infleqtion, which is commercializing the platform.

That said, the structural facts carry weight for R&D managers tracking quantum software procurement. Superstaq operates across multiple hardware modalities — Sandia's trapped-ion QSCOUT, Berkeley Lab's superconducting testbed, and now SQMS's superconducting systems — which positions it as one of the few cross-platform software layers embedded in federally funded user facilities. For labs and vendors weighing build-versus-buy decisions on quantum compilation and instruction management, a platform already running at three DOE testbeds since 2021 offers a longer operational track record than most competitors can show.

The renewals also signal that DOE's quantum testbed infrastructure, funded through the National Quantum Information Science Research Centers and related programs, continues to attract commercial software partners as the systems grow. Berkeley Lab's Spitzer frames the value proposition in workflow terms: reliable access to software tools as hardware evolves underneath the experiments.

Broader DOE footprint

Beyond the three announced partnerships, Infleqtion's DOE engagement includes ongoing work with Argonne National Laboratory and the National Laboratory of the Rockies (NLR), including a recently awarded ARPA-E initiative on quantum-powered energy grid optimization.

Infleqtion positions the deals as part of a strategy to deliver scalable quantum software to government, academic and commercial users. The company, which builds neutral-atom systems for computing, networking, sensing and security, counts the U.S. Department of War, NASA, the U.K. government and NVIDIA among its users and collaborators, and says it published with NVIDIA the first demonstration of a materials science application using logical qubits.

For research managers at DOE-adjacent institutions, the practical question going forward is whether Superstaq's cross-platform claims translate into measurable efficiency gains as testbeds scale — a question the renewed Sandia and Berkeley agreements, with their emphasis on reliability at growing system sizes, are now structured to answer.
