This project is an excellent match with the goals of the Applied Quantum Technologies CDT, as it clearly aims to connect foundational quantum science with real-world applications. Accurate time and frequency dissemination underpin nearly every quantum technology, from quantum clocks and sensors to synchronised quantum networks. Developing robust methods for optical transfer of time and frequency references addresses one of the CDT’s central themes: enabling scalable, deployable quantum systems supported by a national metrology infrastructure.
The project builds upon the UK’s leadership in precision measurement through the National Physical Laboratory (NPL) and the National Timing Centre and aligns with the strategic objectives of the UK NQTP through engagement with the QuSIT and QEPNT Hubs. It will provide an essential link between laboratory-based frequency standards and applied systems operating in the field — from fundamental physics experiments to commercial quantum communication trials.
Through the CDT, the student will receive comprehensive training in optical metrology, laser stabilisation, feedback control, and photonics, along with opportunities for close collaboration with NPL and industrial partners developing timing and sensing technologies. The project offers a strong platform for interdisciplinary development, combining optics, atmospheric physics, and control systems engineering.
Beyond its technical goals, the work supports the CDT’s broader mission of translating quantum science into usable technology. By developing compact, resilient, and traceable optical timing links, the research contributes to future infrastructures for distributed quantum sensing, coordinated telescope arrays, and national timing resilience, positioning the UK at the forefront of time–frequency dissemination technology.
Students will gain hands-on experience with state-of-the-art instrumentation, collaborate with leading national labs, and contribute to innovations that underpin next-generation timing systems for space, telecommunications, and quantum sensing. The project offers opportunities for high-impact publications, conference presentations, and interdisciplinary training—making it an exceptional platform for a future career in quantum technologies.
Graduates from this project will be highly sought after in both academia and industry for their expertise in precision measurement, optics, and control systems. The work on optical metrology and time & frequency standards opens career opportunities in academia, national labs, and at national metrology institutes, such as NPL. The expertise gained is also directly applicable to the growing quantum technology and photonics industries, particularly in precision timing, navigation, and communication systems, and for aerospace and defence sectors that are working on radar synchronisation, satellite time transfer, or high-stability reference systems.
The project’s combination of fundamental physics and practical engineering ensures that the graduate will emerge as a highly capable experimental physicist and systems engineer, well-equipped to lead innovations in precision timing and applied quantum technologies.
The supervisor holds a joint appointment at NPL and the University of Strathclyde. The candidate will be supported in working directly with NPL throughout the project.
