Two concepts of noncontextuality in quantum mechanics

Autor: Hofer-Szab��, G��bor

There are two different and logically independent concepts of noncontextuality in quantum mechanics. First, an ontological (hidden variable) model for quantum mechanics is called noncontextual if every ontic (hidden) state determines the probability

Context. Hot subdwarfs experienced strong mass loss on the red giant branch (RGB) and are now hot and small He-burning objects. These stars constitute excellent opportunities for addressing the question of the evolution of exoplanetary systems direct

On the three types of Bell's inequalities

Autor: Hofer-Szab��, G��bor

Bell's inequalities can be understood in three different ways depending on whether the numbers featuring in the inequalities are interpreted as classical probabilities, classical conditional probabilities, or quantum probabilities. In the paper I wil

Quantum mechanics as a noncommutative representation of classical conditional probabilities

Autor: Hofer-Szab��, G��bor

The aim of this paper is to analyze the reconstructability of quantum mechanics from classical conditional probabilities representing measurement outcomes conditioned on measurement choices. We will investigate how the quantum mechanical representati

Approaching the UCT problem via crossed products of the Razak-Jacelon algebra

Autor: Barlak, Sel��uk, Szab��, G��bor

We show that the UCT problem for separable, nuclear $\mathrm C^*$-algebras relies only on whether the UCT holds for crossed products of certain finite cyclic group actions on the Razak-Jacelon algebra. This observation is analogous to and in fact rec
