International Business Machines advances to Stage C of DARPA quantum program
International Business Machines was selected for Stage C of DARPA's Quantum Benchmarking Initiative. Independent experts would test its path to a fault-tolerant quantum computer ahead of a first system expected in 2029.
What happened
International Business Machines was selected for Stage C. Stage C was the third phase of the Quantum Benchmarking Initiative (QBI) led by DARPA. In that phase, independent experts extensively tested and measured quantum hardware, technology, systems engineering, and architectures to determine if a company could build a fault-tolerant quantum computer. According to the company, the assessment covered both devices and the engineering and design choices behind them.
Providence, one of the largest health systems in the United States, had 119,000 caregivers. With AI and automation, hiring managers reduced administrative effort by 90%. Internal caregivers started their new roles on average 12 days sooner. Providence also lowered transfer costs by 60% and improved process accuracy by up to 70%.
Independent review gives investors outside check on quantum claims
"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 expected to deliver the first fault-tolerant system in 2029. According to the company, the statement linked the advance to the strength of its technical route.
According to the company, the value for the business lay in external validation rather than internal testing. For investors, review by independent experts offered a clearer basis to assess technical claims about hardware and systems engineering. Efficiency gains from AI and automation in hiring administration illustrated how applied technology could affect operating effort and accuracy. That distinction between developer claims and examiner review helped to place technical progress in perspective.
DARPA timetable and research use sketch quantum background
DARPA launched the QBI in 2024 to determine whether an industrially useful fault-tolerant quantum computer could be built. DARPA aimed to determine whether such a system could be built by 2033. According to the company, that question defined the purpose of the initiative and the horizon against which technical work was judged. The description distinguished the program goal from the work of any participating company.
