Can a useful quantum computer be built by 2033? Asks DARPA.

Stage A is to describe a utility-scale quantum computer concept (defined as one whose computational value exceeds its cost) that has a plausible path to realisation in the near term. 

Stage B is to describe an R&D plan capable of realising the utility-scale quantum computer, the risks associated with the plan and the planned risk mitigation steps, as well as the prototypes needed to reduce the risks. 

Stage C is to work with the government to verify and validate that the utility-scale quantum computer concept can be constructed as designed and operated as intended.

Stage A, involved 18:companies, in November 2025, DARPA selected 11 companies to enter Stage B and may still add others and two companies are currently in Stage C.

The organisations being evaluated are here 

In addition to funding, the programme will provide unbiased third-party verification and validation of an organisation’s approach.

The Stage A contract opportunity opened in March 2026 and concludes on Sept. 30, 2026. Organisations that have not yet been funded are invited to join. “Of particular interest are entrants with distinct approaches that have not yet been evaluated,” says DARPA.

Selected participants will enter Stage A, a six-month period in which they will describe a full system concept and provide evidence supporting its feasibility.
