John Bell Workshop 2014

Published by on | 1 Response

Bell’s theorem has been called “the most profound discovery of science”. However, there have been controversies on the deep implications of the theorem. The main purpose of this online workshop is to highlight the existing debates and address the controversies. Another purpose is to get some constructive inputs to the forthcoming Bell volume edited by Mary Bell and Shan Gao. This… Read more →

Experimental tests of Bell inequalities

Published by on

Marco Genovese Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” 1964 was a wonderful year for physics, in this “annus mirabilis”, summarising and simplifying a little, quark model was proposed by Gell-Mann and Zweig and charm and colour properties were introduced, Higgs published his work on the scalar boson, $\Omega$ boson and CP violation were discovered,… Read more →

Quantum Solipsism and Non-Locality

Published by on | 8 Responses

Travis Norsen Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” J.S. Bell’s remarkable 1964 theorem showed that any theory sharing the empirical predictions of orthodox quantum mechanics would have to exhibit a surprising — and, from the point of view of relativity theory, very troubling — kind of non-locality. Unfortunately, even still on this 50th anniversary,… Read more →

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

Published by on | 2 Responses

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

Published by on

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 →

Local Beables and the Foundations of Physics

Published by on

Tim Maudlin Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” John Bell’s most celebrated contribution to the foundations of physics is his famous theorem. The theorem demonstrates that any physical theory capable of generating the predictions of the standard quantum-mechanical algorithm, in particular the prediction of violations of Bell’s inequality for experiments done at space-like separation,… Read more →
