when i read about quantum correlation , its written that quantum entanglement violates bell inequalities. But in every book we always take bell states as a example of entanglement. I am cofused that either bell states are classically correlated or quantum correlated ? …

I saw somewhere that the famous Bell's inequalities in quantum theory are related to the distributive law in the classical set theory. Is this true? More precisely, the inequalities are consequences … violation of the inequalities justifies the quantum theory vs pure classical one. Please hint where can I read it about? …

I have recently seen some presentation slides of Michał Horodecki (slide number 77) in which he discussed the following conjecture. Bound entangled states satisfy all Bell inequalities The … conjecture is not true for multi-partite systems, and the references are given in the talk itself. I believe by now, the bipartite case is also settled, one way or the other. Bell theorem has some …

Is it possible to prove Bell inequality starting from a state formed from triplet states, i.e. $\frac{1}{\sqrt{2}}(|\uparrow>_A|\uparrow>_B+|\downarrow>_A|\downarrow>_B)$? If not, why? I do not …

All the experiments I know, which have been performed to test Bell inequalities, are somehow based on measuring the spin degree-of-freedom of some particle (usually photons, sometimes electrons). I …

While deriving and proving Bell-type inequalities of the form $|E(a,b)-E(a,b')|+|E(a',b)+E(a',b')|\leq 2$ I know that the conditions on the operators $O_a$ and $O_b$ are that they must be bounded …

Consider the Bell setting, where Alice and Bob get inputs $x,y$ and they perform measurements $\{M^x_a\}_a,\{N^y_b\}_b$ respectively on their shared pure state $\Psi_{AB}$ to obtain outputs $a,b … $. Resulting conditional probability distribution is $p(a,b|x,y)$. We have the famous Bell's inequality, and its various alternative formulations, which are upper bounds on the linear combinations of the …

From a purely mathematical standpoint, does Bell Inequality favor De Broglie-Bohm over other interpretations of QM? I have a superficial understanding of all this but it seems to me that BellInequality is about non-locality and entanglement which are some of the key features of de Broglie-Bohm. "Moreover, a hidden variable interpretation of elementary quantum theory (5) has been explicitly …

As its well known, quantum correlations break Bell's inequalities only to a certain limit called the Tsirelson's bound. The bound was written for the CHSH inequality. My question is what is the Tsirelson bound for the original case that Bell dealt with in his article, and how it is proven. …
