Ehrenfest Award ceremony in Vienna, December 2016


De Haagse Hogeschool

I am lecturer (docent) in applied physics at The Hague University of Applied Sciences (De Haagse Hogeschool), location Delft. From 2015 until 2021 I worked as  researcher in the Quantum NanoPhotonics group of Prof. Dr. Val Zwiller at KTH in Stockholm. My research in Stockholm focused on excitons in cuprous oxide. I did experimental studies on giant Rydberg excitons and on excitonic Bose-Einstein condensation. On this website you can find my CV, publications, research interests, and contact details. You can find my publications and citations also at Google Scholar.

Loophole-free Bell test

From May 2014 until October 2015 I worked in the group of Prof. Dr. Anton Zeilinger in Vienna. There we performed a loophole-free Bell test with quantum entangled photons. 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.
