For the next Quantum Engineering Grenoble Seminar || Quantum Foundations we are pleased to welcome Jean Bricmont from the Catholic University of Louvain (UCL), who will give 2 talks next week.
The de Broglie-Bohm theory as a rational completion of quantum mechanic.
Tuesday, March 26, 14:30

Abstract:
We will first explain why ordinary quantum mechanics provides an extremely accurate method for predicting results of experiment carried out in laboratories
but does not tell us what is happening outside of them.
Then, we will give a sketch of the de Broglie-Bohm theory and emphasize why what is usually called « measurements », are in reality interactions between microscopic systems and laboratory instruments. Understanding that interaction allows us to derive the usual quantum mechanical algorithm for predicting results of experiments.


Schrödinger’s paradox and proofs of non locality without inequalities
Wednesday, March 27, 11:00am 

Abstract:
Proofs of non locality usually combine the EPR argument showing that either certain specific « hidden variables » exist or there are instantaneous actions at a distance, with Bell’s inequalities showing that the first possibility is ruled out, leaving only the second one, namely non locality.
We will give a more direct proof based on an extension by Schrödinger of the EPR argument combined with standard no hidden variables theorems; this proof basically does not necessitate any experimental test.
