We study quantum devices through low-temperature electronic transport measurements. Our goal is control at the level of single charge, single flux quantum, single photon and single phonon, enabled by fundamental physical phenomena such as superconductivity, the Josephson effect, flux and charge quantisation, and quantum entanglement. The ability to control and measure quantum states in nanoscale solid-state devices makes them a promising platform for new quantum technologies. Applications include quantum computing and quantum simulation, quantum encryption, quantum metrology, and novel sensors operating beyond the standard quantum limit.
Work within this activity includes:
- Quantum Metrology: superconducting and hybrid charge pumps for accurate definitions of the ampere.
- Graphene & 2D materials: transport phenomena in 2D materials including hydrodynamic flow and the superconducting proximity effect.
- Ultralow temperature thermometry and devices: developing the techniques required to undertake quantum transport measurements at electron temperatures below 1 millikelvin.
- Semiconductors: Transport properties of narrow band-gap semiconductor heterostructures and nanostructures
- Nanoelectromechanics: using nanoscale cantilevers to probe properties of quantum fluids.
