Quantum contextuality for rational vectors
Adan Cabello, Jan-Åke Larsson
The Kochen-Specker theorem states that noncontextual hidden variable models are inconsistent with the quantum predictions for every yes-no question on a qutrit, corresponding to ev…
Memory cost of quantum contextuality
Matthias Kleinmann, Otfried Gühne, José R. Portillo +2
The simulation of quantum effects requires certain classical resources, and quantifying them is an important step in order to characterize the difference between quantum and classi…
Compatibility and noncontextuality for sequential measurements
O. Gühne, M. Kleinmann, A. Cabello +5
A basic assumption behind the inequalities used for testing noncontextual hidden variable models is that the observables measured on the same individual system are perfectly compat…
