IonQ (NYSE: IONQ), the quantum computing firm headquartered in College Park, Maryland, has advanced to Stage C of the Defense Advanced Research Projects Agency’s Quantum Benchmarking Initiative.
The company and DARPA have signed a Stage C agreement with a potential value of up to $300 million, continuing the validation of IonQ’s approach to large-scale fault-tolerant quantum computing.
Funding beyond the initial obligation remains subject to future appropriations and DARPA funding actions, the company disclosed alongside the announcement.
IonQ is among the first companies selected to reach this final stage, following successful completion of Stage A and Stage B of the program.
DARPA’s Quantum Benchmarking Initiative is designed to determine whether quantum computing systems can reach utility scale, where their computational value exceeds their cost.
During Stage A, IonQ defined the technical concept for a utility-scale quantum computer, while Stage B involved developing a detailed research and development roadmap with risk-mitigation plans.
Stage C, which runs through 2029, will subject multiple generations of IonQ’s Superion quantum systems to DARPA’s independent verification and validation process.
“Advancing to Stage C is a significant vote of confidence in IonQ’s technology roadmap and architecture for delivering quantum computing at utility scale,” said Niccolo de Masi, IonQ Chairman and CEO.
De Masi added: “We’ve long believed that winning the quantum race requires more than achieving technical milestones. It requires building systems that can be manufactured reliably and at scale, and that are designed to solve some of the world’s most complex problems.”
He emphasized that this ambition is already materializing, stating: “That’s not a future promise — it’s happening today, with our sixth-generation quantum computer, Superion 256.”
Chris Ballance, IonQ President of Quantum Computing, highlighted the company’s manufacturing philosophy as central to its competitive approach.
“Radical simplification and rapid scale are at the heart of how we build,” said Ballance. “The path to scale isn’t more complexity — it’s stripping complexity out, so systems can be manufactured, deployed, and operated reliably at volume.”
Ballance framed DARPA’s rigorous testing process as an opportunity, saying that independent verification is now putting that manufacturing discipline to the test.
Throughout the QBI process, IonQ plans to continue scaling manufacturing and deployment of Superion systems while expanding its customer base across commercial, scientific, and security sectors.
IonQ’s customer and partner ecosystem includes Amazon Web Services, AstraZeneca, and NVIDIA, with earlier systems delivering a reported 20x performance increase over previous quantum solutions.
In 2025, the company set a world record in quantum computing performance by achieving 99.99% two-qubit gate fidelity, a benchmark that reinforces the credibility of its technical roadmap.
