چکیده

WARNING This is a revised version with respect to the one submitted on Mon, 3 Jul 2000. By mistake an earlier version and not the final one was submitted. Abstract 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.

Ε´/ε Violates Bell's Inequality

We formulate a set of Bell's inequalities for the system of two correlated neutral kaons coming from the decay of a φ-meson, without assuming CP and CP T invariance. We show that a non-vanishing value of the phenomenological parameter ε ′ would violate such inequalities, ruling out Bell's locality.

On “ Bell ’ s inequality without alternative settings ”

Cabello has recently (in quant-ph/0210081) observed that " ...an EPR-experiment with a fixed POVM on each particle provides a violation of Bell's inequality without requiring local observers to choose between the alternatives. " In this note I discuss the implications of this observation for tests of locality.

We discuss the role of two fundamental assumptions locality and realism in Bell's considerations. We demonstrated that by deriving an analogue of Bell's inequality for conditional probabilities it is possible to prove directly (i.e., without appealing to the locality assumption) that Bellian realism is incompatible with quantum mechanics

Bell inequality and the locality loophole: Active versus passive switches

All experimental tests of the violation of Bell’s inequality suffer from some loopholes. We show that the locality loophole is not independent of the detection loophole: in experiments using low efficient detectors, the locality loophole can be closed equivalently using active or passive switches.

Violation of local realism with freedom of choice.

Bell's theorem shows that local realistic theories place strong restrictions on observable correlations between different systems, giving rise to Bell's inequality which can be violated in experiments using entangled quantum states. Bell's theorem is based on the assumptions of realism, locality, and the freedom to choose between measurement settings. In experimental tests, "loopholes" arise wh...

Bell's Theorem, Non-Separability and Space-Time Individuation in Quantum Mechanics

We first examine Howard's analysis of the Bell factorizability condition in terms of 'separability' and 'locality' and then consider his claims that the violations of Bell's inequality by the statistical predictions of quantum mechanics should be interpreted in terms of 'non-separability' rather than 'non-locality' and that 'non-separability' implies the failure of space-time as a principle of ...
