The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is seeking information from potential sources capable of providing a tunable single frequency laser as part of its efforts to develop quantum networks. The procurement aims to acquire a laser that meets stringent specifications for stability and performance, which are critical for the active phase stabilization of fiber links in quantum information distribution. This laser will play a vital role in replicating state-of-the-art classical phase stabilization methods before integrating quantum measurement techniques. Interested parties should respond to the notice by contacting Joni L. Laster or Forest Crumpler via email, with responses due by January 20, 2025, at 11:00 AM Eastern Time. The government intends to issue a Sole Source Award to NKT Photonics, Inc. if no other capable sources are identified.
