November 6, 2025 — YORKTOWN HEIGHTS, New York \u2013 IBM (NYSE: IBM<\/a>) today announced it has been selected for Stage B, the second of three stages of the Quantum Benchmarking Initiative led by DARPA, the United States Defense Advanced Research Projects Agency.<\/p>\n As the independent research and development arm of the U.S. Department of Defense, DARPA\u2019s work focuses on identifying, creating, and supporting transformational, high-reward technologies for national security. In 2024, DARPA launched the Quantum Benchmarking Initiative (QBI) to determine the feasibility of building an industrially fault-tolerant quantum computer whose computational value exceeds its cost.<\/p>\n The program is designed to rigorously validate and verify multiple approaches towards delivering such a quantum computer by 2033.<\/p>\n \u201cIBM\u2019s progression to Stage B of DARPA\u2019s Quantum Benchmarking Initiative is a firm validation of IBM\u2019s approach to delivering a large-scale, fault-tolerant quantum computer,\u201d said Jay Gambetta, Director of IBM Research. \u201cIBM has publicly laid out our comprehensive plan and roadmap to scale quantum computers towards fault-tolerance. As the industry advances, we look forward to working with DARPA as they continue an unbiased review of potential viable strategies across the field.\u201d\u00a0<\/p>\n QBI aims to support the Stage B \u201cperformers\u2019\u201d ongoing research and development efforts through third-party verification and validation of their strategy.<\/p>\n As part of the initiative, IBM is also aiming to explore novel approaches to scaling control systems for quantum computers with SEEQC<\/a>.<\/p>\n Each successful QBI performer will progress through three stages of the program:<\/p>\n

\n\tStage A required an initial technical concept of a cost-effective, fault-tolerant quantum computer that has a plausible path to realization in the near term. Stage A performers were announced in April 2025.
\n\tAnnounced today, Stage B called for a comprehensive research and development plan capable of realizing such a quantum computer, as well as the risks associated with this plan and mitigation approaches.
\n\tStage C, according to DARPA<\/a>, will be when \u201cthe QBI independent verification and validation (IV&V) team will test the companies\u2019 computer hardware.\u201d
