The Trapped Ion Quantum Technology Group invites applications for a PhD position in experimental quantum physics. The project focuses on building and operating a 2D ion-trap platform for open-system quantum simulations using trapped Rydberg ions, within the ERC Synergy project OPEN-2QS. Research will explore fast quantum interactions and long-term stability to simulate novel states of matter, quantum thermodynamics, and molecular dynamics. The candidate will work in an experimental environment and collaborate with partners at the Universities of Mainz and Tübingen, contributing to next-generation quantum simulation technologies.
