Real-world sensors frequently encounter limitations in sensitivity or accuracy due to inherent imperfections. To overcome these challenges, we utilise atomic vapour systems that provide best-in-class sensitivity and accuracy within a compact sensor footprint. In addition to sensing applications, we are also exploring the potential of these vapour systems in quantum information technologies. 

The magnetometers we are developing enable fast, non-invasive, and direct measurement of nerve activity beneath the skin. This offers clinicians a valuable tool for gaining deeper insights into a range of neurological disorders, potentially leading to more accurate diagnoses and improved treatments. These magnetometers can also enhance public safety when deployed by homeland security agencies, allowing for high-throughput, chemical-specific detection of explosives and illicit narcotics. Furthermore, by identifying anomalies in the Earth’s magnetic field, they can support mineral exploration and aid in locating hidden structures or exploded buried ordnance.
