Geometric measures of discordlike quantum correlations based on Tsallis relative entropy (1811.11453v2)
Published 28 Nov 2018 in quant-ph
Abstract: In this paper we formulate a kind of new geometric measure of quantum correlations. This new measure is in terms of the quantum Tsallis relative entropy and can be viewed as a one-parameter extension quantum discordlike measure that satisfies all requirements of a good measure of quantum correlations. It is of an elegant analytic expression and contains several existing good quantum correlation measures as special cases.
