The extended semantic realism (ESR) model reinterprets quantum probabilities as conditional rather than absolute probabilities, which provides a general framework that assumes local realism and incorporates the mathematical apparatus of standard quantum mechanics (SQM). We discuss expectation values, sequential measurements and correlation functions within this model. Then, we consider the standard Bell-Clauser, Horne, Shimony and Holt (BCHSH) inequalities and show that they must be replaced by modified BCHSH inequalities. These contain detection probabilities that are not predicted by SQM and do not depend on features of the measuring apparatuses or environment. In order to avoid contradiction, the detection probabilities must satisfy some no-violation conditions which can be experimentally checked, at least in principle, and make the ESR model falsifiable.

Abstract
The extended semantic realism (ESR) model reinterprets quantum probabilities as conditional rather than absolute probabilities, which provides a general framework that assumes local realism and incorporates the mathematical apparatus of standard quantum mechanics (SQM). We discuss expectation values, sequential measurements and correlation functions within this model. Then, we consider the standard Bell-Clauser, Horne, Shimony and Holt (BCHSH) inequalities and show that they must be replaced by modified BCHSH inequalities. These contain detection probabilities that are not predicted by SQM and do not depend on features of the measuring apparatuses or environment. In order to avoid contradiction, the detection probabilities must satisfy some no-violation conditions which can be experimentally checked, at least in principle, and make the ESR model falsifiable.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
