Bell's Theorem, Non-Separability and Space-Time Individuation in Quantum Mechanics
نویسندگان
چکیده
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 individuation for quantum-mechanical systems. And I find his arguments for both claims to be lacking.

Non-separability does not relieve the problem of Bell’s theorem
This paper addresses arguments that “separability” is an assumption of Bell’s theorem, and that abandoning this assumption in our interpretation of quantum mechanics (a position sometimes referred to as “holism”) will allow us to restore a satisfying locality principle. Separability here means that all events associated to the union of some set of disjoint regions are combinations of events ass...
متن کاملOn the solution of the EPR paradox and the explanation of the violation of Bell’s inequality
A new theory is proposed offering a consistent conceptual basis for nonrelativistic quantum mechanics. The Einstein-Podolsky-Rosen (EPR) paradox is solved and the violation of Bell’s inequality is explained by maintaining realism, inductive inference and Einstein separability.
متن کاملEntropic Bell Inequalities
We derive entropic Bell inequalities from considering entropy Venn diagrams. These entropic inequalities, akin to the Braunstein-Caves inequalities, are violated for a quantum mechanical EinsteinPodolsky-Rosen pair, which implies that the conditional entropies of Bell variables must be negative in this case. This suggests that the satisfaction of entropic Bell inequalities is equivalent to the ...
متن کاملN-partite Separability Inequalities Exponentially Stronger than Local Reality Inequalities
For an N -partite quantum system we show that separability implies inequalities on Bell correlations which are stronger than the local reality inequalities by a factor 2. PACS numbers : 03.65.Ud, 03.67.-a ⋆ E-mail: [email protected] 1
متن کاملQuantum Nonlocality and Inseparability
wK = 1. A necessary condition for separability is derived and is shown to be more sensitive than Bell’s inequality for detecting quantum inseparability. Moreover, collective tests of Bell’s inequality (namely, tests that involve several composite systems simultaneously) may sometimes lead to a violation of Bell’s inequality, even if the latter is satisfied when each composite system is tested s...
