How to bid on Quantum Benchmarking Initiative Topic (QBIT) Stage A for DARPA

What DARPA is buying and why it matters

The Defense Advanced Research Projects Agency (DARPA) is seeking innovative research for its Quantum Benchmarking Initiative Topic (QBIT) Stage A. They are looking for approaches to build utility-scale, fault-tolerant quantum computers and to develop workflows that use quantum computing.

This opportunity focuses on revolutionary advances in the design, engineering, testing, and evaluation of such systems, rather than incremental improvements. Vendors should propose work that offers new and distinct contributions to the field.

Key dates and what happens at the deadline

This solicitation was published on July 29, 2026. The deadline for submissions is November 30, 2026, at 9:00 AM ET. All proposals must be submitted by this time.

Late submissions are typically not accepted, so it is crucial to finalize and submit your response well in advance of the deadline.

Who this opportunity suits

This opportunity is best suited for firms and research organizations capable of delivering major advances in quantum computing. It is intended to encourage new entrants to DARPA's Quantum Benchmarking Initiative (QBI).

While prior QBI or US2QC performers are not precluded from submitting, their proposals must offer new or distinct contributions to the initiative. This is a professional services category opportunity, focusing on research and development.

Practical tips for a competitive response

Focus your proposal on revolutionary advancements. DARPA explicitly states they are not looking for evolutionary improvements to existing practices. Clearly articulate how your approach represents a significant leap forward in quantum computing design, engineering, testing, or evaluation.

If you have previously worked on QBI or US2QC solicitations, ensure your current proposal highlights genuinely new and distinct contributions. Simply re-submitting similar work will likely not be competitive. Clearly differentiate your new approach.

Pay close attention to all instructions within the solicitation documents once you access them. Adhering strictly to formatting, page limits, and content requirements is essential for a compliant and competitive submission. Start preparing your response early to allow ample time for review and refinement.
