I lead now a group sharing the same passion. In my previous life, I measured how strong electric fields change the magnetic moment of the electron, studied quantum chaos, ran quantum gates, characterized entangled states, and teleported quantum information over 10 micrometers. Notable current achievements of my group are ultra low-noise ion traps, 3D-printed ion traps, control over a quantum rotor, and trapped elecrons.

After completing my undergraduate studies, I decided to pursue engineering-oriented research. Hartmut’s lab is the perfect place for me, as trapped ion systems lie at the intersection of physics and engineering."
