The first quantum revolution, based on wave-particle duality, started in the early 1900's. It dramatically modified our vision of the microscopic world. It permitted the invention of technologies that have dramatically changed the society. The second quantum revolution is based on a yet stranger concept, entanglement. We do not know yet if it will impact the society as much as the first quantum revolution.

5 Questions:

Why do you speak of two quantum revolutions? Isn’t it the same theory ?
What was the bottom line of the debate between Einstein and Bohr?
Why did you receive a Nobel prize for a debate that started 90 years ago? Wasn’t it already settled?
Are they really useful applications of quantum physics?
What is a quantum computer?

Talk by

Alain Aspect

Alain Aspect is Professor at Institut d’Optique of Université Paris-Saclay. He was awarded the 2022 Nobel Prize in Physics "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science".

Music by

EÄ

Born from the meeting of Jonathan Bruyninx (guitar), Adeline Ghilain (flute), and Marielle Vancamp (violin, nyckelharpa), Eä is a young Belgian folk group offering a repertoire of original compositions, along with traditional pieces and songs rearranged for the occasion.

Eä - two simple, clear letters with a touch of originality - come from a fantasy universe (in Elvish, a language invented by Tolkien, it means "let it be") and perfectly match the group's music: poetic, finely arranged, with a hint of whimsy and a Celtic flair that suits them well. Whether they lead you into a dreamlike reverie or an exhilarating melody, the three members of Eä are far from done making you dance!
