Postdoctoral Fellow in Ion Trap Quantum Computing Paul Scherrer Institute (PSI) in Switzerland

The Paul Scherrer Institute (PSI) in Switzerland is offering a postdoctoral fellowship in Ion Trap Quantum Computing within the Ion Trap Quantum Computing Group and the Quantum Computing Hub at the Laboratory for Nano- and Quantum Technologies (LNQ). PSI is the largest research institute for natural and engineering sciences in Switzerland, renowned for its interdisciplinary and innovative research environment. The institute employs over 2300 staff and is committed to training future generations of scientists.

This postdoctoral position focuses on operating and further developing a complex ion trapping experiment based on the QCCD architecture, utilizing both passive and active integrated photonics. The successful candidate will develop scalable approaches for controlling ions in a multi-zone trap array, contribute to the design and implementation of experimental control systems, optical and laser setups, and implement protocols for quantum computing and quantum sensing experiments. Collaboration with a multidisciplinary team of PhD students, technicians, and engineers is a key aspect of the role.

Applicants must have a PhD in Physics or a closely related field, ideally with experience in experimental ion trapping or neutral-atom optical tweezer platforms. Relevant peer-reviewed publications, demonstrated ability to design, operate, and troubleshoot complex quantum physics experiments, and hands-on experience in optics and lasers, atomic physics, cryogenics and ultra-high vacuum systems, real-time control systems for quantum experiments, and integrated photonics are highly desirable. Proficiency in data analysis, scientific documentation, strong teamwork and communication skills, and experience with co-supervision of students are expected.

PSI offers systematic training on the job, personal development opportunities, and a supportive vocational training culture. The employment contract is limited to 2 years. The institute provides modern employment conditions and on-site infrastructure to support work-life balance.

Applications must be submitted online by 31 May 2026, including a list of publications and addresses of referees. For further information, candidates may contact Dr Julian Schmidt or Dr Cornelius Hempel via email. The application portal is available at this link.
