English: Originally from Augsburg, Germany, I studied Interdisciplinary Sciences and Physics at ETH Zürich, Switzerland, where I worked a little bit on randomness extractors in the context of quantum cryptography. Recently, I moved to Vienna and joined the group to write my Master’s thesis on quantum thermodynamics. We are interested in how one can include feedback mechanisms into the theoretical description of quantum clocks and what fundamental limits to the clock’s performance exist in the presence as well as in the absence of feedback. In state-of-the-art atomic clocks feedback mechanisms are generically implemented by the interaction between a laser (acting as a clockwork) and an atomic transition (acting as a frequency reference).
