Quantum DetectionThe 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.
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.
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
