Michael Chwalla


Michael Chwalla’s research is focused on the aspects of precision spectroscopy, optical atomic clocks, and ultra-fast gates using ion trap experiments. Part of this work is influenced by experiments on quantum computation where techniques and advanced methods can be transferred to high-resolution spectroscopy in order to improve the measurement precision or profit from especially designed, decoherence-free states.↵
