The 22nd edition of the European Conference on Foundations of Physics, largely devoted to the 100th anniversary of quantum theory, took place on June 30 - July 2, 2025. This year's event was hosted by the International Centre for Theory Of Quantum Technologies (ICTQT) and the Faculty of Mathematics, Physics and Informatics of the University of Gdańsk!

The European conference on the foundations of physics has been organised since 1992 by the British Philosophy of Physics Society. Individual editions are held in different countries and are co-organised by invited partners. For the first time in history, the event took place in Poland! The International Centre for Theory Of Quantum Technologies (ICTQT) and the Faculty of Mathematics, Physics and Informatics of the University of Gdańsk were invited to co-organise FOUNDATIONS 2025. Organisational support was provided by the Foundation for the Development of the University of Gdańsk.

The choice of co-organisers for this year's edition was not accidental - the main theme was quantum theory, its structure, interpretation, paradoxical predictions and philosophical consequences. Quantum mechanics was born exactly 100 years ago, almost to the day. For over 35 years, the University of Gdańsk has been conducting research in the field of multiphoton quantum interferometry and quantum information theory. Some of this research, such as the theory of entanglement swapping, the result of collaboration between prof. Marek Żukowski and prof. Anton Zeilinger, contributed to the 2022 Nobel Prize for this famous Austrian scientist. An international research team established in 2018 at the ICTQT UG, led by Prof. M. Żukowski, is conducting intensive research in the field of quantum technology theory, financed mainly from European funds.

During three intensive days, scientists from all over Europe (and beyond!) took part in three discussion panels on topics such as gravity in the context of quantum entanglement, the history and philosophy of quantum mechanics, and the definition of space-time. Among the distinguished speakers were dr hab. Karol Horodecki, prof. UG, prof. Christine Aidala from the University of Michigan and dr Jorge Alberto Manero Orozco from the Czech Academy of Sciences.

‘We are very proud to have been entrusted with co-organising this important event’,’ said prof. Marek Żukowski, head of the conference. ‘I am very happy that it is here, in Poland, in Gdańsk, in the 55th anniversary year of the University of Gdańsk, that we were able to celebrate the 100th anniversary of quantum research in such a special way.’

‘We are very happy that we were able to host such an important conference at our Faculty and co-organise it,’ said the Dean of the Faculty of Mathematics, Physics and Informatics, dr hab. Marcin Marciniak, prof. UG. ‘This event is part of a series of initiatives we are undertaking to promote quantum topics. I would like to remind you that the next Q-Camp Quantum Summer School will take place from 25 August to 4 September, and on 29 August, the Q-Con Quantum Conference (https://qcon.tech) will be held, a technology and business conference dedicated to the prospects for the development of quantum technologies.’

The conference was accompanied by a poster session.

The book of abstracts is available here. Over 90 speeches were delivered.
