Progressing quantum magnetometry in defence and security applications, such as airborne navigation and maritime situational awareness requires reliable low size, weight and power (SWaP) sensors to be used in conjunction with complementary sensing modalities (e.g. sonar, gravimetry, ground penetrating radar). Data fusion with these technologies makes new requirements for quantum magnetic sensors which are best addressed by development of devices exploiting microfabrication of optical-atomic systems to achieve better encapsulation and ruggedisation. Development of integration of light sources, polarising optics and detection into the microfabricated atomic cell will be a significant enabling step in the transfer of quantum magnetometers from an R&D prototype to a reproducible, reliable and scalable component. The development of these techniques will exploit recent advances in photonic integration. New research in optical magnetometry of use in biomedical applications, such as unshielded magnetoencephalography and transcranial magnetic stimulation, will also inform the development of novel sensing schemes enabling higher dynamic range and measurement responsivity.

By combining the development of fundamental underpinning techniques in microfabrication and atomic sensing modalities with production and trials for prototype devices, this studentship will generate exciting new results in sensor science along with carefully directed impact with end-users.
