Simulation of quantum contextuality with invasive-measurement maps

These are the data used to generate the figures of the paper "Simulation of quantum contextuality with invasive-measurement maps". ABSTRACT: Contextuality is a defining feature that separates the quantum from the classical descriptions of physical systems. Building upon the marginal-scenario framework, we introduce a general method to characterize contextuality through stochastic linear maps. These maps effectively model invasive measurements on an otherwise classical statistics, relating probabilities within the noncontextuality polytope that includes all classical probabilities to probabilities outside the polytope. Our approach provides a systematic way to simulate contextuality from classical resources, enabling the identification of the structural properties of such maps. Moreover, it offers a quantification of contextuality based on the invasiveness cost, i.e., a property intrinsic to the maps themselves, rather than to the probabilities they act upon.
