ion traps

At neQxt, our theory team explores the principles that make scalable quantum computing possible. We study how fault tolerance can be realized under realistic conditions, designing circuits, developing simulation methods, and analyzing noise at the circuit level. A key part of our work is to understand trade-offs between different approaches and how they can be embedded into modular architectures. We aim to connect theoretical insights with practical feasibility, developing techniques that move fault tolerance closer to realization. By building tools, models, and architectures, we provide a bridge between abstract principles and the requirements of physical quantum processors.

2 PhD and 2 PostDoc positions are available in the ion trapping laboratory at Palacky University in Olomouc, Czechia. The positions will be funded within the 5 year Centre of Excellence and are available in the following research directions:
- engineering of quantum nonlinear interactions between photons and phonons in trapped atomic ions,
- realization of the photonic coupling between ions in Paul traps and optically levitated nanoparticles,
- development of the molecular ion source with Helium nanodroplets precooling for quantum logic spectroscopy.

PhD and postdoc positions are available in the group of Prof. Stefan Willitsch at the University of Basel (Switzerland) on the development of quantum technologies for single trapped molecular ions and their application in precision spectroscopy.

Project description

You will be working in the lab with ion traps from day one, but you don’t need to come in as an expert. We are looking for outstanding scientists who are keen to contribute to our mission. We particularly value fields involving coherent control of quantum systems, whatever form it takes (our current team comes from backgrounds including ions, atoms, and quantum dots).

You will be working to solve unique, never-before-solved challenges with a world-class team of scientists and engineers. We work across fields including algorithm design, microfabrication, opto-mechanical engineering, vacuum design, and radiofrequency electronics.

PhD and postdoc positions are available in the group of Prof. Stefan Willitsch at the University of Basel (Switzerland) on the development of quantum technologies for single trapped molecular ions and their application in precision spectroscopy and the control of molecular collisions and interactions.
