Quantum Detection Quantum Detection

The Quantum Detection Group at NPL uses a broad range of technology, much of it at the nanometre scale, to explore physical phenomena for electrical metrology, magnetic sensing and communications.

Research areas

  • NPL is developing superconducting devices and associated measurement systems for signal processing at cryogenic temperatures.
  • Structural and functional engineering, physics and metrology of graphene.
  • Measurements and visualisation of small magnetic fields/moments.
  • Nanoscale superconducting quantum interference devices.
  • Nano-electromechanical systems (NEMS).
  • NPL is developing nano-scale devices for moving electrons one at a time around an electrical circuit. These devices may form the foundation of a future redefinition of the SI base unit for current, the ampere.
  • Technology to facilitate quantum optical processes and algorithms.
  • Superconducting quantum technology and hybrid systems.

Featured

NPL’s research into the quantum Hall effect was highlighted in Nature

What we do

  • Research and develop new devices for generating and detecting individual quanta (e.g. phonons or magnetic spin)
  • Work on new techniques for characterising quantum-mechanical state evolution
  • Use quantum coherence and entanglement to enhance measurement precision
  • Develop high speed devices for manipulation of electrical current at the single-electron level
  • Study the latest materials, such as graphene, to advance our understanding of the quantum effects that lie at the heart of the modern measurement system
