Here, you can find more information on my research interests and the projects I am currently working on, along with some videos and posters I have prepared for various occasions.
Fusion categories and CFTs
I investigate the connection between fusion categories and conformal field theories via lattice models in one and two dimensions.
This approach is driven by the question whether there is a CFT associated to a specific fusion category, namely one that arises from the Haagerup subfactor.
If you want to know more about this, you can find my PhD thesis on the arXiv: arXiv:2101.04154

Quantum Information Theory
I am interested in various aspects of quantum information theory, but especially in quantum key distribution. This is the task of establishing a secure key between two spatially separated parties that can safely be used in any cryptographic application.

During the summer semester 2020, I have held a seminar on the security of quantum key distribution, which was held as an online seminar. The videos can be found on youtube:
Quantum Machine Learning
As machine learning is successfully used in numerous applications, there are many attempts to transfer these ideas to the realm of quantum computation. I am intereseted in designing fully quantum neural networks that are capable of processing quantum data.
