Bell on Bell’s theorem: The changing face of nonlocality

Harvey R. Brown and Christopher G. Timpson Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” Between 1964 and 1990, the notion of nonlocality in Bell’s papers underwent a profound change as his nonlocality theorem gradually became detached from quantum mechanics, and referred to wider probabilistic theories involving correlations between separated beables. The proposition that standard quantum mechanics… Read more →

Measurement and Macroscopicity: Overcoming Conceptual Imprecision in Quantum Measurement Theory

Gregg Jaeger Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” John S. Bell, of course, is most well known for the result now referred to simply as “Bell’s theorem”, which removed from consideration the class of so-called local hidden-variable theories which at the time of its publishing appeared to be the most natural class of theories… Read more →

What did Bell really prove?

Jean Bricmont Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” The goal of this paper is to give a pedagogical introduction to Bell’s theorem and its implication for our view of the physical world, in particular how it establishes the existence of non local effects or of actions at a distance. We also discuss several misunderstandings… Read more →
