The Defense Advanced Research Projects Agency (DARPA) is seeking information on the application of quantum entanglement in novel sensing technologies through its Request for Information (RFI) identified as DARPA-SN-25-18. The objective is to gather insights that will guide future investments in quantum sensor architectures and interconnects, focusing on two main research thrusts: Heterogeneous Architectures for integrating various quantum media and Homogeneous Architectures aimed at enhancing entangled sensor systems. This initiative highlights the potential of quantum entanglement to improve measurement precision and reduce noise in sensing applications critical to defense and research. Responses to the RFI are due by January 15, 2025, and interested parties can contact the BAA Coordinator at DARPA-SN-25-18@darpa.mil for further information.
