Key Researchers in Contextuality

Researchers whose work is most directly connected to the study of Kochen-Specker sets, quantum contextuality, and non-locality:

• Adán Cabello (Sevilla) — KS sets, graph-exclusivity principle, Bell non-locality vs. contextuality
• Robert Spekkens (Perimeter) — Generalized contextuality, epistemic models, resource theories
• Matt Leifer (Chapman) — Ontological models, psi-ontology theorems, fine-tuning
• Caslav Brukner (Vienna) — Reconstruction of quantum theory, indefinite causal order
• Lucien Hardy (Perimeter) — Causal inference, quantum gravity, reconstructions of QM
