The Department of Defense, specifically the Department of the Air Force, is seeking sources for a 3He4He dilution refrigerator to support research in solid state silicon quantum computing at the United States Air Force Academy (USAFA). The required dilution refrigerator must achieve temperatures of 10 mK or lower, provide a cooling power of at least 500 µW at 100 mK, and include specific features such as a cryogen-free solenoid magnet, vibration isolation, and a sample space volume of at least 30 liters. This procurement is critical for the department's research program, which focuses on creating and studying quantum computing qubits. Interested vendors are encouraged to submit a capabilities package to the primary contact, Aurora Santos, at aurora.santos@us.af.mil, or the secondary contact, Kristin Heikkila, at kristin.heikkila@us.af.mil, including relevant company information and product specifications by the specified deadline.
