De Haagse Hogeschool
Since 2021, I am lecturer (docent) in applied physics at The Hague University of Applied Sciences (De Haagse Hogeschool), location Delft. I teach several courses and supervise research projects. Together with lecturers from four universities of applied Sciences (The Hague, Amsterdam, Fontys and Saxion) we are developing a new master programme on Applied Quantum Technology. The rapidly growing field of quantum technology needs well-educated quantum engineers. I am also part of the Delt/Leiden Talent and Learning Centre.
Nobel Prize in Physics 2022
Congratulations to Alain Aspect, John Clauser, and Anton Zeilinger for the Nobel Prize in Physics! With their most challenging experiments on entangled photons, they have demonstrated that quantum mechanics is true, even in situations where our intuition shouts: 'This cannot be possible!' Measurements on distant photons show correlations that are not possible to understand in a local realist world, that is, in a world where particles have properties before any measurement and where there are no interactions backward in time. Einstein called these correlations 'spooky action at a distance'. Besides fundamentally changing our understanding of nature, the great experiments of these Nobel laureates started and promoted the field of quantum information science, which is now booming.
Vienna Hofburg Loophole-free Bell test
From May 2014 until October 2015 I worked in the group of Anton Zeilinger in Vienna. There, we performed a significant-loophole-free Bell test with quantum entangled photons in the basement of the Hofburg. We addressed the detection loophole, the locality loophole and the freedom-of-choice loophole in one experiment. Therefore, our experiment shows in a most conclusive way that physical objects do not have measurable properties before these properties are actually measured, or that there exist physical interactions that go faster than light. Read our article in PRL (open access).
This publication was awarded the Paul Ehrenfest Best Paper Award for Quantum Foundations for the year 2015. It was also awarded the Best Paper Award of the Austrian Academy of Science (ÖAW) from the Jubiläumsfonds der Stadt Wien. In 2022, Anton Zeilinger won the Nobel Prize 'for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.'
KTH
From 2015 until 2021 I worked as researcher in the Quantum NanoPhotonics group of Val Zwiller at KTH in Stockholm. My research in Stockholm focused on the quantum physics of excitons in cuprous oxide. I did experimental studies on giant Rydberg excitons and on excitonic Bose-Einstein condensation.
