Postdoc in quantum computing at the University of Konstanz, in the group of Guido Burkard.

Previously, I was a PhD candidate in theoretical physics at QuSoft and the University of Amsterdam, in the group of Jasper van Wezel.

My main research interest is the interface of many-body physics and quantum computation.

For a recent layman's introduction to quantum simulation, quantum computation, and the work in my thesis, see here here (English) or here (Dutch).

For an even broader introduction to quantum computation, see the pop-sci articles below. They were originally published in Dutch on www.quantumuniverse.nl. Machine translations, which are quite good, are available.

In 2022/2023 I organised the QAMBS seminar, a monthly seminar/journal club/reading group on Quantum Algorithms for Many Body Systems.

Preprint out on Line-graph qubit routing: from kagome to heavy-hex and more. (08/06/2023)

Our preprint on the "Ability of error correlations to improve the performance of variational quantum algorithms" is published in Phys. Rev. A **107**, 042426 (2023) as editors' suggestion. (21/04/2023)

Our preprint on the "Variational quantum eigensolver for the Heisenberg antiferromagnet on the kagome lattice" is published in Phys. Rev. B **106**, 214429 (2022).
