Simultaneous elements of reality for incompatible properties by exploiting locality

TL;DR

This paper demonstrates that quantum correlations and locality can be exploited to assign simultaneous elements of reality to incompatible properties, challenging traditional interpretations and proposing a new measurement scheme involving two correlated particles.

Contribution

It introduces a novel physical setup that allows simultaneous objective values for incompatible observables using correlations between two spin particles.

Findings

Quantum correlations can be used to assign simultaneous elements of reality.

The proposed setup involves measurements on two correlated spin particles.

Traditional ideal experiments are inadequate for this purpose.

Abstract

We show that the extensions of quantum correlations stemming from a "strict" interpretation of the criterion of reality of Einstein, Podolsky and Rosen raise the inadequacy of their ideal experiment for the assignment of simultaneous elements of reality to two incompatible properties. Then, we suggest a different physical situation enabling the simultaneous assignment of objective values of two incompatible observables of a spin particle by means of measurements of two compatible properties of a second correlated spin particle.
