Program Solicitation: Heterogeneous Architectures for Quantum (HARQ)

Background
The Defense Advanced Research Projects Agency (DARPA) is seeking proposals for the Heterogeneous Architectures for Quantum (HARQ) program. The goal of this contract is to advance the field of quantum computing by exploring innovative approaches that lead to significant advancements in theory, devices, and system concepts. This includes research into quantum interconnects, quantum circuit compilers, distributed algorithms, resource estimation, quantum memory/repeater devices, quantum frequency converters, and microwave-to-optical transducers.

The agency emphasizes that proposals should not focus on evolutionary improvements but rather on revolutionary advancements that align with DARPA's mission to enhance national security through early technology investments.

Work Details
Proposals must address the following key areas:
- Innovative approaches to quantum interconnects and circuit compilers.
- Development of distributed algorithms and resource estimation techniques.
- Creation of quantum memory/repeater devices and frequency converters.
- Exploration of hardware-software integration within the quantum computing stack.
- Identification of major technical risks associated with the proposed research and clear plans for mitigation.

Proposals should demonstrate overall scientific and technical merit, relevance to DARPA's mission, and a realistic budget that reflects an understanding of the necessary level of effort and staffing.

Period of Performance
The period of performance will be defined in accordance with the specific proposals submitted, detailing the expected timeline for research activities and deliverables.
