Future Program Announcement & Proposers Day: Heterogeneous Architectures for Quantum (HARQ) DARPA-SN-25-98
Summary
AI-generated · Aug 24, 2025Solicitation seeks innovative proposals toward realizing heterogeneous quantum computing architectures, exploring revolutionary approaches for quantum interconnects, quantum circuit compilers, distributed algorithms, resource estimation, quantum memory/repeater devices, quantum frequency converters, microwave-to-optical transducers, and other elements at the interface of quantum hardware and software. It excludes research that primarily yields evolutionary improvements to the current state of practice. Feedback on goals, metrics, and scope is invited via HARQ@darpa.mil, with a final program description to follow; a virtual Proposers Day will be held to support the HARQ solicitation, with registration and meeting details provided in the Proposers Day section.
There are two similar notices for HARQ that differ in the Proposers Day date and the program solicitation number, while the core scope remains the same. DARPA plans to release the HARQ program solicitation prior to Proposers Day, and the notices indicate final program details and the specific PS will be published ahead of the event. Businesses should monitor for the final PS and Proposers Day details to determine eligibility and how to participate.
DARPA anticipates soliciting innovative proposals towards the realization of heterogeneous quantum computing architectures. Proposed research would investigate innovative approaches that enable revolutionary advances in theory, devices, and system concepts for quantum interconnects, quantum circuit compilers, distributed algorithms, resource estimation, quantum memory/repeater devices, quantum frequency converters, microwave-to-optical transducers, and other elements at the interface of the quantum computing hardware/software stack. Specifically excluded is research that primarily results in evolutionary improvements to the existing state of practice. See Future Program Details section below. DARPA welcomes feedback on the HARQ program goals, metrics, and scope outlined in Future Program Details section below. Feedback should be emailed to HARQ@darpa.mil no later than July 30, 2025, at 5:00 p.m ET, after which time DARPA will post the final PS. DARPA will host a virtual Proposers Day in support of DARPA Program Solicitation (PS) DARPA-PS-25-XX for HARQ on August 20, 2025, via webcast from 11:00 a.m. to 4:00 p.m. ET. DARPA anticipates releasing DARPA-PS-25-XX prior to Proposers Day. See Proposers Day Details section below for additional registration and meeting details.
