Open positions

Join the Trapped-Ion Quantum Engineering Group

We are constantly looking for motivated (to-be) ion trappers to join our team! If you are interested in a Bacherlor's thesis, undergraduate work, Master's thesis, PhD thesis or postdoctoral researcher position, please contact Christian Ospelkaus! 

Postdoc position available on microwave trapped-ion quantum logic project

Microfabricated surface-electrode ion trap

Trapped ions are a leading platform for the implementation of future quantum computers and simulators. We develop techniques for implementing quantum logic gates using microwave fields. This holds great promise for integrating the generation of control fields with a scalable platform based on microfabrication. Our group has developed a scalable multilayer technology for surface-electrode ion traps. We have recently demonstrated a two-qubit gate with a fidelity of 98.4% using a custom integrated waveguide. We aim to use these techniques to implent high-fidelity quantum logic operations and quantum simulations with ions in surface-electrode trap arrays.

We are looking for a postdoctoral researcher responsible for experiments on quantum simulations and quantum logic with ions in cryogenic surface-electrode traps. The position at Leibniz Universität Hannover is for three years with the possibility of extension. The salary is according to TV-L E13 (100%). 

The official tender can be found here. For further information please contact Christian Ospelkaus.
