IBM Advances to Stage C of DARPA Quantum Benchmarking Initiative
The selection moves IBM beyond conceptual assessments into independent verification of its quantum hardware.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
IBM (IBM) has been selected for Stage C, the third phase of DARPA's Quantum Benchmarking Initiative, moving into independent hardware testing.
IBM completed the first two stages, which assessed technical concepts, research and development plans, and risk mitigation approaches. Stage C's independent experts will test hardware and evaluate engineering and architectures to determine whether IBM can build a fault-tolerant quantum computer, designed to operate despite errors. IBM expects to deliver its first such system, IBM Quantum Starling, in 2029. DARPA's program seeks to determine whether a system whose computational value exceeds its cost can be built by 2033.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

IBM moves to third phase of DARPA's rigorous evaluation of approaches to building a fault-tolerant quantum computer

"Advancing to the third stage of DARPA's Quantum Benchmarking Initiative validates the strength of IBM's path to building a fault-tolerant quantum computer," said Jay Gambetta, Director of IBM Research and IBM Fellow. "IBM expects to deliver the first fault-tolerant system in 2029, and we plan to scale the value of quantum computing well beyond that timeline. We look forward to working with DARPA's team of experts as they advance their review of approaches to fault-tolerant quantum computing into the testing phase."
As an independent research and development arm of the
IBM has built the strongest quantum foundation in the industry, anchored by the largest fleet of quantum computers across the globe and Qiskit, the world's most popular quantum software. IBM's quantum computers are already being used today as scientific tools by a network of more than 340 organizations across financial services, healthcare, materials science, academia, and government as they build industrial applications and pursue algorithms to unlock the full potential of fault-tolerant quantum computing.
Last year, IBM laid out its plans to deliver the world's first fault-tolerant quantum computer, IBM Quantum Starling. Starling will combine advances in error correction, processor design, systems engineering, and more. Since then, IBM's progression has remained on course, including the demonstration of core hardware components for fault tolerance and breakthroughs in efficient error correction decoding.
Advancing to Stage C
Each successful QBI performer has progressed through three stages of the program thus far:
- Stage A required organizations to submit an initial technical concept of a cost-effective, fault-tolerant quantum computer that has a plausible path to realization in the near term. Several Stage A performers were announced in April 2025.
- Stage B called for a comprehensive research and development plan from each company detailing how to realize such a quantum computer, as well as the risks associated with this plan and mitigation approaches.
- Announced today, those selected for Stage C will move beyond conceptual plans and progress to evaluation by DARPA's QBI independent verification and validation (IV&V) team as they test the companies' hardware.
Alongside its participation in QBI, IBM continues to collaborate with partners across industry, government, and academia to accelerate the timeline toward fault-tolerant quantum computing.

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
What does IBM's selection for DARPA Quantum Benchmarking Initiative Stage C mean?
IBM will move beyond conceptual assessments into independent testing and evaluation. DARPA's verification team will test hardware and assess technology, systems engineering and architectures to determine whether IBM can build a fault-tolerant quantum computer.
When does IBM expect to deliver its first fault-tolerant quantum computer?
IBM expects to deliver its first fault-tolerant quantum system in 2029. The planned system is IBM Quantum Starling; the timing remains an expectation rather than a completed milestone.
