A11: Feedback control for quantum information processing

Principal investigator:

Prof. Dr. Felix von Oppen

Project summary:

Maintaining coherence in the face of interactions with the environment is essential for reliably manipulating quantum states and thus quantum information processing. One prominent strategy towards this goal relies on the measurement of error syndromes and subsequent active quantum error correction. Such error correcting codes typically rely on projective syndrome readout. In practice, such projective measurements may be too difficult or too time consuming. In this project, we explore feedback-based strategies towards this goal which use weak rather than projective measurements, with a focus on topological quantum computation and the underlying adiabatic quantum dynamics.
