Information-theoretic Bell inequalities based on Tsallis entropy

Year: 2015

Type: article

Abstract: We numerically investigate entropic Bell inequalities for a pair of entangled qutrits using information-theoretic distances. We show that for this class of inequalities the Tsallis entropy is more suitable than the Shannon entropy, as it reveals nonclassicality for a larger set of quantum states. Finally, we find that, like probability-based inequalities, entropic ones are maximally violated by the non--maximally entangled qutrit state.
