2017 Andrew Carnegie Lecture: Professor Alain Aspect

From the Einstein-Bohr debate to quantum information: A new quantum revolution.
Professor Aspect explores the quantum entanglement debate which lasted throughout the careers of Albert Einstein and Neils Bohr. Using the now celebrated ‘Bell’s Inequalities’, Professor Aspect has shown that quantum entanglement is indeed a reality. In other words, Einstein’s local realist world view is incorrect.
This revelation has prompted an emergence of a new field of quantum information, and Professor Aspect shows how these conceptual discussions will form the very heart of the second quantum revolution.
