Jonas Helsen


Room B205
Wehner Group

I am a PhD student working on the topics of quantum information theory and quantum computing. Specifically my interests include the validation and verification of quantum computers and networks, quantum error correction codes, large scale quantum architectures and somewhat more abstractly the role of symmetric structures in quantum information theory.

In my free time I enjoy reading everything I can get my hands on, playing music (usually with fellow students) and bouldering. I’m also always up for a board game.
