Entanglement Zoo II: Examples in Physics and Cognition

We have recently presented a general scheme enabling quantum modeling of different types of situations that violate Bell’s inequalities [1]. In this paper, we specify this scheme for a combination of two concepts. We work out a quantum Hilbert space model where ‘entangled measurements’ occur in addition to the expected ‘entanglement between the component concepts’, or ‘state entanglement’. We e...

Correlation functions, Bell’s inequalities and the fundamental conservation laws

I derive the correlation function for a general theory of two-valued spin variables that satisfy the fundamental conservation law of angular momentum. The unique theory-independent correlation function is identical to the quantum mechanical correlation function. I prove that any theory of correlations of such discrete variables satisfying the fundamental conservation law of angular momentum vio...

Lab1: Entanglement and Bell’s Inequalities

In this laboratory, entanglement as one of the key concepts in quantum mechanics was introduced, and we concentrated on the polarized entangled photons. Bell’s inequality was used as a criterion of quantum and classic. The polarized entangled photons were created by Spontaneous Parametric Down-Conversion in Beta Barium Borate crystals. The coincidence counts were measured as the number of entan...

Violation of Bell’s inequality for continuous variables

We construct a wide class of bounded continuous variables observables that lead to violations of Bell inequalities for the EPR state and give an intuitive Wigner function explanation how to predetermine which operators won’t ever exceed the bounds given by local theories.
