Information-Theoretic and Operational Measures of Quantum Contextuality
New information-theoretic and operational measures of quantum contextuality are introduced and applied to the KCBS scenario, showing that optimal uncertainty states have vanishing operational contextuality while high-contextuality states obey nontrivial Robertson bounds, achieved by distinct states.
