Abstract We show that contextual hidden variables including the effect of measuring devices can be backward-propagated by means Green's function to initial Cauchy data. If this data is uncorrelated in spacelike-disjoint sets, CHSH-Bell inequality derived. However, correlation loophole remains unclosed.

Analyzing pseudo-telepathy graph games, we propose a way to build contextuality scenarios exhibiting the quantum supremacy using graph states. We consider the combinatorial structures generating equivalent scenarios. We investigate which scenarios are more multipartite and show that there exist graphs generating scenarios with a linear multipartiteness width.

abstract stylistics is a critical approach focusing lexically, intellectually, and literally on the text to extract main literary elements of the text. as a result, literary text can be supposed as its basis and in fact, stylistics is originated from the text. this analytic-descriptive study is to analyze a poem by …….(1983-1940) as one of the outstanding pioneers of literary movement in eg...

Recently, several inequalities involving sequences of measurements have been proposed which hold for non-contextual models but which are violated in quantum mechanics. They also have been found to be violated in experiments and the violation is independent of the prepared quantum state. A typical contextual model explaining this violation uses a classical memory. We investigate the required mem...

We establish a link between contextuality of quantum mechanics and quantum-mechanical computation. Specifically, we show that no deterministic measurement-based quantum computation evaluating a non-linear function can be described by a non-contextual hidden-variable model. We give examples for such computations derived from quantum codes with suitable transversality properties, and from a count...
