Dr Markus Rambach

Research Fellow

Faculty of Science

Overview

Dr. Markus Rambach's research interests are in the field of quantum optics, especially on single photon sources to create photonic qubits and qudits.

Markus was born and raised in a small alpine town in Austria, before doing his BSc and MSc at the University of Innsbruck (Austria). He did his undergrad in Physics, before completing an MSc in experimental quantum physics in the prestigious group of Pro. Rainer Blatt. Here, is where he met a young renegade Brit who had just completed his PhD in the research group of Prof. Andrew White at the University of Queensland. Inspired by the stories, Markus decided to have a look for himself and moved to Brisbane, where he completed his PhD with Andrew in 2017. After a short intermezzo for a Postdoc in Scotland, he moved back to Brisbane 2019 and has been a research fellow at UQ ever since. Markus' research interests are in the weird but beautiful world of quantum physics, where he is investigating ways to make the upcoming quantum internet a reality. Over the years he has worked with verious single photon platforms and used them for quantum information experiments. Recently he changed gear and is now investigating the infinitely-sized space of higher-dimensional quantum systems, so-called qudits.

Markus enjoys community engagement, be it as chair of the SMP Early and Mid-Career Academics Committee or as a member of the EQUS Public Engagement Committee. He particular likes the sparks in people's eyes when they start to understand a concept or idea.
