John Teufel (Fed)


Dr. John D. 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.
