Ling Hao

Principal Research Scientist

Prof. Ling Hao received the BSc degree in general physics and the MSc degree in solid state physics from Beijing Normal University, China. She moved to the UK in 1992 and received the PhD degree at the Department of Physics and Applied Physics, University of Strathclyde, UK, for research on electronic noise in superconducting devices in 1995. Since then she has worked at NPL. 

She is leading a team in the Quantum Detection Group, researching into quantum sensors based on superconductivity, microwave resonators and nano-mechanical systems (NEMS). She is a Fellow of the Institute of Physics, Chartered Physicist and a visiting professor at Imperial College London, Fudan University (Shanghai) and Harbin Institute Technology, China.  She has published more than 180 research papers in refereed journals as well as writing five book chapters. She holds two international patents in the area of SQUIDs and microwave detection. She was a member of the Institute of Physics Superconductivity Committee and is a Member of Editorial Board of IEEE Council on Superconductivity, responsible for Detectors. She was Guest Editor for recent Special Issue on NanoSQUIDs for ‘Superconducting Science & Technology’. She has managed a number of projects, both national and international including as co-ordinator for EU funded projects. In her time at NPL she has co-supervised more than 10 PhD students at universities including Imperial College, UCL, Manchester and Surrey Universities. 

Areas of interest

She is leading work on applications of superconducting electronics, nanoscience and microwave technology for quantum measurements. The aim is towards single particle detection and metrology using nanoscale Superconducting QUantum Interference Devices (nanoSQUIDs) and nanoelectromechanical system (NEMS) resonators. She is also prominent in developing graphene, 2D materials and other thin film transport measurement methods using patented microwave resonator techniques.

  • Investigation of quantum limits of NanoSQUIDs sensors
  • Development of microwave nanoSQUIDs for single spin detection and & manipulation
  • Development of novel inductive superconducting transition edge detectors (ISTED) for single photon and massive particle measurements
  • Near-field microwave and SQUIDs excitation and readout techniques for NEMS using quantum materials
  • Novel coupled microwave resonator technique for x-ray detection
  • Early stage product development for non-contacting microwave methods for graphene electrical properties
