💡 Open Thesis Ideas

I am always looking for great students who are passionate about science and highly intrinsically motivated to work on cutting-edge research ideas. If this applies to you and you are looking for an opportunity to write your thesis (BA & MA) in the field of quantum computing, or work as Research Assistant (HiWi) in this field, please feel free to write to me personally or apply via our thesis form (Anfrage Abschlussarbeiten). I also offer the supervision of individual internships (Einzelpraktika) for 6 or 12 ECTS. If you are interested, please contact me.
Please understand that first experiences in quantum computing are urgently required, since a short-term familiarization with our topics is hardly possible. Note: Supervision capacities may vary, but there are usually enough research topics available.

The following topics are generally of interest:

  • Quantum Generative Adversarial Networks
  • Parameterized Hamiltonians
  • Entanglement in Variational Algorithms
  • Pre-training & Hyperparameter Optimization for Quantum Circuits/Algorithms
  • Problem Instance Comparison
  • Detecting Solution-paths for Quantum Applications
  • Quantum Use-Cases
  • Quantum Workflows (only EP)
