Job description

We invite applications for a full-time postdoctoral position in Quantum Technology within the ITCM Group at the University of Sussex, led by Prof Matthias Keller. This position is funded by the Innovate UK project ‘CIFS - Calcium Ion Frequency Standard’, which aims to commercialise a portable atomic clock system being developed at the University of Sussex.

The consortium consists of leading companies in the Quantum Technology, Telecommunication and Defense sectors, such as TMD, Chronos, Leonardo, Covesion, BT and others.. The objective is to build a miniaturized portable optical atomic clock based on a single calcium ion, with an accuracy at the 10-15 level or better. The final system must be able to operate outside a laboratory environment, and must be suitable for production by standard industrial processes.

Over the last years, researchers at the ITCM group have developed a rugged and compact spectroscopy unit, which is based on an all-fibre-coupled ion trap, an ultra-compact laser module providing all the necessary lasers to run the ion trap and the electronic control boards governing the autonomous operation of the system, in addition to an ultra-stable clock laser unit. All subsystems are based on fibre-integrated designs to provide robust and maintenance free operation while keeping a compact size.

The successful candidate will be joining the Portable Atomic Clock team in the ITCM group. Their main focus of work will be updating the current sub-systems to take full advantage of the latest advances in laser and fibre technology, and to integrate them into a fully functioning portable optical clock. Focus will be on the system’s performance and manufacturability, as well as developing and optimising novel spectroscopy schemes to improve the clock’s stability and accuracy.

This position offers an exciting opportunity to work closely with academic and industry partners, pushing some of the latest scientific and engineering developments into real-world applications.

Please get in contact with Prof Matthias Keller for 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.
