Marek Żukowski is a Polish theoretical physicist working in the fields of quantum foundations and quantum information theory. He has played a central role in the development of modern quantum physics in Europe.
Currently Professor at Physics at the University of Gdańsk, Marek Żukowski is also the founding director of the International Centre for Theory of Quantum Technologies (ICTQT).
Scientific achievements
Marek's research focuses on the fundamental aspects of quantum mechanics, in particular Bell’s theorem, quantum entanglement, and the limits of classical descriptions of physical reality. Among his key ontributions is the development of the concept of entanglement swapping in the early 1990s together with Anton Zeilinger and collaborators, which shows that two particles can become entangled without ever directly interacting. Entanglement swapping has since become a fundamental building block of quantum communication and quantum networks.
His work further extended the implications of Bell-type inequalities to more complex systems, including higher-dimensional and multi-particle states, helping to deepen the understanding of nonlocal correlations and their role in quantum theory.
Żukowski has also made important contributions to multiphoton interferometry and quantum optics, providing theoretical frameworks that support experimental advances in quantum information science.
