Professor Artur Ekert will trace the fascinating journey of Bell's inequalities in the field of quantum theory. Originating in the seminal work of John Bell in 1964, these inequalities have appeared as a litmus test for the integrity of quantum theory. Despite first skepticism, later experiments, led by figures such as John Clauser and Alain Aspect, showed the violation of Bell's inequalities, opening new perspectives for exploration. Ekert, drawing on his pioneering work, will explain how these inequalities went from philosophical reflections to practical tools, especially in the field of cryptography. His presentation will highlight the transformative potential of quantum theory, not only in theoretical physics, but also in the revolution of secure communication protocols.

After the talk, Luz Roncal, Ikerbasque researcher at the BCAM will interview him and moderate the colloquium with the audience. Given the boost of quantum technologies, a mailbox has been set up for the public to ask questions to the guest.

IKUR Quantum Talks are organized by Donostia International Physics Center (DIPC), the University of the Basque Country (UPV/EHU) and the Basque Center for Applied Mathematics (BCAM) to raise awareness of the scientific basis and potential of quantum technologies. With public lectures and colloquia for the scientific community in Bilbao and Donostia, this program is part of the IKUR Strategy promoted by the Department of Education of the Basque Country with the support of NextGenerationEU funds through the Complementary Plans (PRTR-C17.I1).
