Quantum mechanics is a well-established theory and its predictions have been experimentally confirmed to great detail. Nevertheless, the foundational meaning of the theory remains elusive. The apparent non-locality, the behaviour of a quantum state upon measurement, and the status of the wavefunction are subjects that still lead to a lot of debate. In my PhD I want to experimentally probe and test such foundational concepts. In the group of Ronald Hanson in the Department of Quantum Nanoscience of the TU Delft, we study the quantum mechanical behaviour of spins in diamond, over which we have an extensive experimental control. For me, this system forms a great opportunity to look at the foundations of quantum mechanics.

The Casimir Research School helps me by providing courses that help to move my PhD forward. I for example participated in the ‘Electronics for Physicists’ course that addresses the power and pitfalls of the electronics that I come across in the lab on a daily basis. I look forward to the rest of my four years as a PhD student in the Casimir School, not only to participate in more courses like this, but also to learn about and from research done by others in the School, both in Delft and in Leiden.
