Unifying nonclassical correlation via Tsallis α-entropy and its application in bilocal scenario

Popis výsledku v původním jazyce

This article introduces a new variant of a family of measurement-induced nonlocality (MIN) measures using Tsallis alpha-relative entropy (T alpha E). We show that the proposed MIN measure satisfies all the axioms of a faithful measure of quantum correlation and resolves the local ancilla issue of Hilbert-Schmidt MIN. Analytically, we evaluate the MIN for an arbitrary pure state and 2 x n-dimensional mixed state. We also establish the simple relations between Tsallis MIN and the other MINs available in the literature. Extending the notion of the Tsallis entropy-based MIN, we characterize the nonbilocal correlation in a bilocal scenario and identify the closer connection between the nonlocal and nonbilocal correlation measures.
