The picture seems even more fuzzy. There are, also, classical dynamical

systems, and classical fields, violating Bell's inequality. And we can

realize quantum entanglement ... by classical computers (experiment done).

And, above all, can we use (as Bell did) the classical probability theory in

the quantum domain?

Non-locality and quantum theory: new experimental evidence

Luigi Accardi, Massimo Regoli

Starting from the late 60's many experiments have been performed to verify

the violation Bell's inequality by Einstein-Podolsky-Rosen (EPR) type

correlations. The idea of these experiments being that: (i) Bell's

inequality is a consequence of locality, hence its experimental violation is

an indication of non locality; (ii) this violation is a typical quantum

phenomenon because any classical system making local choices (either

deterministic or random) will produce correlations satisfying this

inequality. Both statements (i) and (ii) have been criticized by quantum

probability on theoretical grounds (not discussed in the present paper) and

the experiment discussed below has been devised to support these theoretical

arguments. We emphasize that the goal of our experiment is not to reproduce

classically the EPR correlations but to prove that there exist perfectly

local classical dynamical systems violating Bell's inequality.

Locality and Bell's inequality

Luigi Accardi, Massimo Regoli

We prove that the locality condition is irrelevant to Bell in equality. We

check that the real origin of the Bell's inequality is the assumption of

applicability of classical (Kolmogorovian) probability theory to quantum

mechanics. We describe the chameleon effect which allows to construct an

experiment realizing a local, realistic, classical, deterministic and

macroscopic violation of the Bell inequalities.

A Proposed Experiment Showing that Classical Fields Can Violate Bell's

Inequalities

Patrick Suppes (Stanford University, USA), J. Acacio de Barros (Federal

University at Juiz de Fora, Brazil), Adonai S. Sant'Anna (Federal University

at Parana, Brazil)

We show one can use classical fields to modify a quantum optics experiment

so that Bell's inequalities will be violated. This happens with continuous

random variables that are local, but we need to use the correlation matrix

to prove there can be no joint probability distribution of the observables.

The Violation of Bell Inequalities in the Macroworld

Diederik Aerts, Sven Aerts, Jan Broekaert, Liane Gabora

We show that Bell inequalities can be violated in the macroscopic world. The

macroworld violation is illustrated using an example involving connected

vessels of water. We show that whether the violation of inequalities occurs

in the microworld or in the macroworld, it is the identification of

nonidentical events that plays a crucial role. Specifically, we prove that

if nonidentical events are consistently differentiated, Bell-type Pitowsky

inequalities are no longer violated, even for Bohm's example of two

entangled spin 1/2 quantum particles. We show how Bell inequalities can be

violated in cognition, specifically in the relationship between abstract

concepts and specific instances of these concepts. This supports the

hypothesis that genuine quantum structure exists in the mind. We introduce a

model where the amount of nonlocality and the degree of quantum uncertainty

are parameterized, and demonstrate that increasing nonlocality increases the

degree of violation, while increasing quantum uncertainty decreases the

degree of violation.
