Job description

We are delighted to offer a full-time research fellowship with the Ion Trap Cavity-QED and Molecular Physics (ITCM) group at the University of Sussex, led by Professor Matthias Keller. Join our team and you will be part of an EPSRC UK-funded consortium working on a novel atomic clock and its applications. The specific research project aims to develop a novel atomic clock scheme for portable systems based on the developments at the University of Sussex.

Our consortium brings together leading teams from the University of Sussex, the University of Loughborough, the National Physical Laboratory and companies from the quantum technology, telecommunication and defense sectors. Our objective is to build a miniaturized portable atomic clock based on a novel interrogation scheme on a single calcium ion, with an accuracy at the 10-14 level or better.

At ITCM, we have developed a novel interrogation scheme for ion-based atomic clocks that promises significantly improved robustness compared to conventional optical atomic clocks. The project aims to demonstrate the novel scheme in an existing system, implement the system on an existing portable system and demonstrate its advantages in real-world settings.

You will join the Portable Atomic Clock team in the ITCM group and demonstrate the novel scheme and its use in portable atomic clock systems.

This position offers an exciting opportunity to work closely with academic and industry partners at the forefront of quantum technology in the UK, translating some of the latest scientific and engineering developments into real-world applications.

The role is based on our campus set in the South Downs National Park just outside the city of Brighton and Hove, close to the coast and less than an hour from London. Our university follows family-friendly and flexible working policies and our group is part of the Sussex Centre for Quantum Technologies.

Please contact Matthias Keller for any informal enquiries.

The University is committed to equality and valuing diversity, and applications are particularly welcomed from women and black and minority ethnic candidates, who are under-represented in academic posts in Science, Technology, Engineering, Medicine and Mathematics (STEMM) at Sussex. 

The University of Sussex values the diversity of its staff and students and we welcome applicants from all backgrounds.
