SummaryThe conflict between the principle of local causes and the predictions of quantum theory is demonstrated in a concise form without using the concept of hidden variables or determinism.RiassuntoSi dimostra il conflitto tra il principio delle cause locali e le predizioni della teoria quantistica in forma concisa e senza usare il concetto delle variabili nascoste o il determinismo… 
Bell’s theorem and the different concepts of locality
SummaryFour definitions of the principle of local causes, each of which, when applied to a theory, leads to a different mathematical property of the theoretical predictions, are considered and
Real and imagined nonlocalities in quantum mechanics
SummaryBell’s inequality is shown to hold only under a condition termed joint measurability, hidden-variable properties being irrelevant. For it actually to be violated another condition must be
Comments on determinism, locality, Bell’s theorem and quantum mechanics
SummaryArguments are given showing that the observed violation of the Bell, Clauser, Horne, Shimony and Holt inequalities may be interpreted within the framework of quantum mechanics without invoking
Conditionals, Probability and Bell’s Theorem
A new version of Bell’s theorem is proved which shows the inconsistency of locality, realism and quantum theory. By using Mermin s technique of randomising over the settings on the measurement
Hidden Variables or Positive Probabilities?
Despite claims that Bell's inequalities are based on the Einstein locality condition, or equivalent, all derivations make an identical mathematical assumption that local hidden-variable theories
Experimental tests of quantum mechanics versus local hidden variable theories
The authors propose new inequalities involving polarisation correlation parameters as tests of local hidden variable theories versus quantum mechanics. These are derived using Bell's formulation of
How to Avoid Peres' “incompatible results of quantum measurements”
It is demonstrated how, in terms of hidden variables, the claimed incompatibility of results of quantum measurements, obtained in a recent work by A. Peres, may be avoided. The new property which


Proposed Experiment to Test Local Hidden Variable Theories.
A theorem of Bell, proving that certain predictions of quantum mechanics are inconsistent with the entire family of local hidden-variable theories, is generalized so as to apply to realizable
Experimental Consequences of Objective Local Theories
A broad class of theories, called "objective local theories," is defined, motivation for considering these theories is given, and experimental consequences of the class are investigated. An extension
Cryptographic approach to hidden variables
An elementary proof of Bell’s theorem on the incompatibility of local hidden−variable theories with quantum mechanics is presented. The proof is based on considerations of error rates in binary
On the Einstein-Podolsky-Rosen paradox
THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional
The usual interpretation of quantum theory is clouded by the following points. (1) Invalid classical concepts are ascribed fundamental status. (2) The process of measurement is not describable within
