Quantum Devices Group


The Quantum Devices Group, part of NIST's Physical Measurement Laboratory, and the Quantum Electronics and Photonics Division, advances measurement science in a variety of fields using state-of-the-art science and technology, especially:

  • quantum effects, including superconductivity
  • low temperatures to reduce thermal noise
  • state-of-the-art lithography to achieve small sizes.
Major activities of the Group include:
  • Josephson array voltage standards, the most complex superconducting integrated circuits in actual use
  • a new temperature standard, based on precision measurement of Johnson (thermal) noise
  • new x-ray and gamma-ray spectrometers, combining the best features of two different earlier devices, now being licensed for commercialization
  • fully multiplexed arrays of ultra-sensitive microcalorimeters and microbolometers for astronomical observation
  • understanding the physics and technology of quantum computing based on current-biased superconducting Josephson junctions
Located at the base of the Flatiron mountains in Boulder, Colorado, the Group draws heavily on its optical and electron beam fabrication capabilities as well as those for creating micro-electromechanical systems (MEMS).
