Quantum Devices Group

Welcome

The Quantum Devices Group, part of NIST's Electronics and Electrical Engineering Laboratory, and the Quantum Electrical Metrology 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, and
  • 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 capacitance standard, based on counting electrons one at a time using nanometer scale tunnel junctions,
  • 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 for astronomical observation,
  • understanding the physics and technology of quantum computing based on current-biased superconducting Josephson junctions, and
  • magnetic devices for forensics and other applications.


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).

Programs/Projects

Quantum Materials and Devices—Quantum coherent materials have become important in magnetic sensors as well as information processing technology. For magnetic sensors, spin-based transport in metals and across tunnel barriers is …

Quantum Sensors—The Quantum Sensors Project develops sensors based on quantum phenomena for spectroscopy, imaging, and other precision measurements for wavelengths from dc through gamma rays. We integrate these …

Quantum Information and Measurements—America's future prosperity and security may rely in part on the exotic properties of quantum mechanics. Research on quantum information (QI) seeks to control and exploit these properties, and …

Quantum Voltage System Development and Dissemination—This project is developing new standards using Josephson junctions, superconductor-based devices whose quantum behavior makes them perfect frequency-to-voltage converters. Project scientists …
