Superconducting quantum sensors 

Superconducting quantum sensors enable the detection of extremely weak electromagnetic signals at the quantum limit, making them attractive for applications requiring highly sensitive and covert sensing. However, their widespread deployment is constrained by the need for cryogenic operation. We are developing quantum sensing devices based on FeSe and other high-temperature superconductors to enable practical operation at elevated temperatures while maintaining exceptional sensitivity. Our research spans materials synthesis, nanofabrication, device characterisation and theoretical modelling to understand the fundamental mechanisms that limit device performance. By identifying and mitigating these limitations, we aim to realise high-performance superconducting quantum sensors, including ultrasensitive magnetometers and single-photon detectors, suitable for deployment in real-world environments.
