PhD in Physics: Open Quantum System Simulations with Trapped Ions at Stockholm University

Job Description

Stockholm University’s Trapped Ion Quantum Technology Group is looking for a PhD student in experimental physics to study open spin-boson systems with trapped ions. The position is part of the QuantERA project CoQuaDis, which studies many-body phases in open quantum systems and aims to use them for sensing and timekeeping, including time-crystal applications. Crystals of trapped ions give long trapping times, controllable interactions and cooling during operation, and the work involves theory partners at the University of Tübingen and IFISC in Mallorca.
