A deep dive into quantum non-locality and its implications
Seeing | Quantum Physics | 2025-02-28

Hans Busstra, together with Essentia Foundation’s research fellow, physicist Lidia Del Rio, talks to Prof. Sandu Popescu about quantum non-locality. Popescu is Professor of Physics at the University of Bristol and a Fellow of the Royal Society. He did pioneering work in what became the field of quantum information and has won both the John Stuart Bell Prize and the Dirac Medal.
