Research
My research focuses on deductive verification of quantum programs. In more detail, I work with Quantum Weakest Preconditions, a method to compute the best predicate, that ensures that a given postcondition holds after the quantum program is executed. I consider quantum programs from a theoretical point of view, that means everything I do is based on linear algebra.
Thesis Projects
If you are interested in writing a Bachelor’s or Master’s thesis about formal verification of quantum programs, don’t hesitate to contact me. It would be good if you have some basic knowledge about quantum computing and/or program logics (e.g. from taking the ‘Introduction to Quantum Computing’ or ‘Probabilistic Programming’ lecture).
