The Department of Energy, through the Berkeley National Laboratory (LBNL), is seeking sources capable of providing superconducting nanowire single-photon detectors (SNSPDs) for a project focused on quantum information science. The SNSPDs must meet specific requirements, including a detection efficiency of at least 85%, a timing jitter below 50 ps, and the ability to operate continuously in cryogenic conditions at 3K. These detectors are crucial for advancing the understanding of quantum decoherence processes, which are significant challenges in the development of quantum technology. Interested parties should submit documented evidence of similar past work and are encouraged to contact Arielle Anoop at aanoop@lbl.gov or 510-486-5519 by February 25, 2025, to express their interest, noting that this Request for Information (RFI) is for informational purposes only and does not guarantee any procurement actions.
