John Teufel is an experimental physicist in the Applied Physics Division of NIST Boulder.  He received his PhD in physics from Yale University on a fellowship from NASA studying superconducting photon detectors.  Now as a project leader in the Advanced Microwave Photonics group at NIST, he uses the tools of nanofabrication and precision microwave measurements at cryogenic temperatures to explore the quantum behavior of macroscopic systems.  This includes development and metrology of superconducting qubits, optomechanical circuits and Josephson parametric technology. Dr. Teufel received a Presidential Early Career Award in Science and Engineering (PECASE) for approaching the quantum limits of precision measurement in mechanical systems as well as a Dept. of Commerce silver medal for seminal research toward future quantum networks.
