Who we are

The field of Quantum Foundations aims at understanding the fundamental concepts and the mathematical framework of quantum physics, with the ambition to better comprehend the theory, to reformulate it, and to propose generalizations that may be relevant for future physics. Since the initial development of quantum mechanics in the 1920’s, its spectacular success notwithstanding, the question of what quantum theory is actually telling us about the world remains largely unanswered. Achieving a better understanding of quantum theory is of paramount importance for its applications and for combining it with other physical theories like General Relativity. Moreover, studying foundational questions often opens up new surprising avenues, as the modern advances in quantum communication and computing demonstrate.

The first Vienna Quantum Foundations Conference is organized by the Institute of Quantum Optics and Quantum Information-Vienna (Austrian Academy of Sciences). Continuing a long tradition of quantum physics in Vienna, the conference brings together leading international researchers in this field to discuss and shape the future of quantum foundations.


Due to the pandemic, the Vienna Quantum Foundations Conference will take place in hybrid form: some of the invited speakers and panelists will be present in person in Vienna, and the other invited talks and the poster sessions will happen online.

Please note that everybody who joins us in person must conform to the “3G rule” as, for example, described here. In a nutshell (details in the link), you must either be tested, or vaccinated, or have recovered from Covid-19.

We will use MeetAnyway as our online platform ( This is a very professional software solutions that admits a wide variety of personal interaction. We hope that this will make the conference almost as fun and productive as an in-person meeting. Detailed instructions for all participants can be downloaded as a PDF file on the Program page.

Registration is now closed.
