Prof Zeilinger

Nobel laureates Aspect and Zeilinger frequent lecturers at Linnaeus University

During the last 20 years, two out of three Laureates of the Nobel Prize in Physics 2022, Alain Aspect and Anton Zeilinger, have been several times in Växjö as keynote speakers at the annual series of international conferences on quantum foundations, information, and probability.

Andrei Krehnnikov, professor of mathematics at Linnaeus University and the driving force behind Linnaeus University's annual conference on quantum physics. The conferenses attracts world leading physicists and mathematicians to Växjö to discuss the latest in quantum theory and quantum technology.

"The main aim of these studies was to test the fundamental properties of micro-world. One of the most mysterious of them is quantum nonlocality, also known as spooky action at the distance (in Einstein's formulation). In philosophic terms, quantum nonlocality implies indivisibility of our world on microlevel." Andrei Khrennikov says about the laureates achievements.

The conference in 2016 was called Quantum and Beyond (QB) and Professor Anton Zeilinger attended to present a lecture on the results that closed all loopholes in the Bell experiment: Results for which Aspect and Zeilinger together with John Clauser now receive the Nobel Prize in Physics.

"During the last 20 years many stars of quantum theory visited Växjö for our conference series. Alain Aspect and Anton Zeilinger gave their talks here a few times including 2016-session on the final experiments in which all loopholes were closed." Andrei Khrennikov says.

The Bell test was created by physicist John Bell in 1964, to test the theory of quantum mechanics against Albert Einstein's concept of local realism, to determine whether "the world really is as strange as quantum physics claims".
