Job description

# Research Fellow in Quantum Technology**About the role**Applications are invited for a 12 months full-time postdoctoral position (with the possibility for extension) in Experimental Quantum Technology at the University of Sussex. Applicants should have obtained a PhD in experimental quantum information, laser- or atomic physics and be able to demonstrate working experience in this field. The appointment is within the framework of the EPSRC Quantum Technology Hub: Quantum Computing via Integrated and Interconnected Implementations. The successful candidate will work in a team of experienced researchers led by Prof Matthias Keller.The aim of the project is to combine two of the most successful techniques in quantum information processing, trapped ions and photons, and use them to create a distributed quantum network. The main challenge is the implementation of an efficient ion-photon interface based on strongly-coupled cavity-QED.We have developed a multi-zone ion trap that incorporates zones for loading, quantum information processing, and a cavity-based ion-photon interface. The first part of the project is to test and characterise the ion trap system and implement a highly efficient ion-photon interface. This involves the setting up and testing of the system as well as simulating and implementing novel schemes for ion-photon entanglement.Based on successful testing of the multi-zone trap, a second system will be established to implement a basic quantum network.**About you**Ideally, you will have a PhD in experimental quantum information, laser- or atomic physics and be able to demonstrate working experience in this field.The project requires working with a complex optical system with diode lasers, ultra-high vacuum systems, and control electronics to operate the experiment. Having experience and a good understanding of such systems is highly beneficial.**About our School**We are a research-intensive School that simultaneously delivers outstanding teaching to our students. As such we aim to be consistently recognised as truly world leading in key areas of our science, by extending the international excellence, impact and visibility of our research. We aim to be within the top UK universities in our discipline areas, attracting high-quality students at both undergraduate and postgraduate levels.We will establish a reputation as having a particularly open, stimulating, collaborative and supportive working environment for both staff and students, enabling the best possible outcomes for research, teaching and learning. We will further enhance our links with non-academic actors on local, national and international scales, and will maximize the impact of our work.**Why work here**Find out more about our reward and benefits package.Find out about our equality, diversity and inclusion.**Further Key Information**Please contact Matthias Keller ([e-mail]) 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.The University of Sussex values the diversity of its staff and students, and we welcome applicants from all backgrounds.**Eligibility**The University requires that work undertaken for the University is performed in the UK.£38,784 to £46,049 per annum, pro rata if part time, Grade 7View full listing on jobs.ac.ukUniversity of SussexSchool of Mathematical and Physical Sciencesjobs.ac.ukPosition DetailsPosition TypeJobSalaryGBP 38,784 to 46,049 per annumContract TypeFixed-Term/ContractHoursFull TimePost DurationOct 20, 2026 - Oct 26, 2026Academic FieldSchool of Mathematical and Physical SciencesLocationFalmer, United KingdomLanguage RequirementsEnglish
