On Bell's theorem for N‐qubits

Fortschritte der Physik, 2003
AbstractWe present a single general Bell inequality that summarizes all possible Bell type constrains on the correlation function for the N‐particle system (i.e., it is a necessary and sufficient condition for the existence of local realistic models for the correlation function).

Strict Hierarchy of Bell Theorems

Second International Conference on Quantum, Nano and Micro Technologies (ICQNM 2008), 2008
As proved by John Bell, quantum mechanics exhibits correlations in spacelike separated bipartite systems that are impossible to reproduce by classical means. There are three levels of "Bell theorems", depending on which aspects of the quantum correlations can or cannot be reproduced classically.

Bell's theorem and Bayes' theorem

Foundations of Physics, 1990
Bell's theorem is expounded as an analysis in Bayesian probabilistic inference. Assume that the result of a spin measurement on a spin-1/2 particle is governed by a variable internal to the particle (local, “hidden”), and examine pairs of particles having zero combined angular momentum so that their internal variables are correlated: knowing something ...
