Graph-theoretic approach to Bell experiments with low detection efficiency
Zhen-Peng Xu, Jonathan Steinberg, Jaskaran Singh +3
Bell inequality tests where the detection efficiency is below a certain threshold can be simulated with local hidden-variable models. Here, we introduce a method to…
Minimal true-implies-false and true-implies-true sets of propositions in noncontextual hidden variable theories
Adán Cabello, José R. Portillo, Alberto Solís +1
An essential ingredient in many examples of the conflict between quantum theory and noncontextual hidden variables (e.g., the proof of the Kochen-Specker theorem and Hardy's proof…
Advances on the Conjecture of Erdős-Sós for spiders
Camino Balbuena, Mucuy-Kak Guevara, José R. Portillo +1
- A hamiltonian graph verifying %with a vertex of degree greater or equal than contains any -spider. - If is a graph with average degree $\bar{d} > k…
Quantum state-independent contextuality requires 13 rays
Adán Cabello, Matthias Kleinmann, José R. Portillo
We show that, regardless of the dimension of the Hilbert space, there exists no set of rays revealing state-independent contextuality with less than 13 rays. This implies that the…
Irreducible triangulations of the once-punctured torus
S. Lawrencenko, T. Sulanke, M. T. Villar +3
A triangulation of a surface with fixed topological type is called irreducible if no edge can be contracted to a vertex while remaining in the category of simplicial complexes and…
Orthogonal Representation of Graphs
Alberto Solís-Encina, José Ramón Portillo
Orthogonal Graph Representations are essential tools for testing existence of hidden variables in quantum theory. As required by the interpretation of Copenhaghe on the foundations…
