Edward J. Gillis In a recent series of papers Wiseman, Cavalcanti, and Rieffel have outlined and contrasted the operationalist and realist views about what we now call Bell’s theorem. They also assert that Bell presented these two different versions at different times. A careful examination of the historic 1964 paper and of the writings of Bell and others that preceded… Read more →
H. M. Wiseman Yes. That is my polemical reply to the titular question in Travis Norsen’s self-styled “polemical response to Howard Wiseman’s recent paper.” Less polemically, I am pleased to see that Norsen has made significant concessions on my position that Bell’s 1964 theorem is different from Bell’s 1976 theorem, and that the former does not include Bell’s one-paragraph heuristic presentation… Read more →
Lev Vaidman Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” It is argued that the lesson we should learn from Bell’s inequalities is not that quantum mechanics requires some kind of action at a distance, but that it leads us to believe in parallel worlds. Vaidman – Bell paper
This is a polemical response to Howard Wiseman’s recent paper, “The two Bell’s theorems of John Bell”. Wiseman argues that, in 1964, Bell established a conflict between the quantum mechanical predictions and the joint assumptions of determinism and (what is now usually known as) “parameter independence”. Only later, in 1976, did Bell, according to Wiseman, fi rst establish a conflict between… Read more →
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 →
The preposterous title of this post is also the title of my contribution to the Special Issue on Quantum Nonlocality and Reality — 50 Years of Bell’s theorem. Abstract: Quantum theory’s violation of remote outcome independence is assessed in the context of a novel interpretation of the theory, in which the unavoidable distinction between the classical and quantum domains is… Read more →
Bernard d’Espagnat Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” Important advancements in scientific knowledge may, not infrequently, be looked at from several angles. Here, for investigating the question the article title defines, part of our attention shall have to be turned on the relationships of Bell’s theorem with the old, but still not fully cleared… Read more →
