On a parametrically extended entanglement-measure due to Tsallis relative entropy
Shigeru Furuichi
Abstract
In the previous paper FYK, we mainly studied the mathematical properties of Tsallis relative entropy with respect to the density operators. As an application of it, we adopt a parametrically extended entanglement-measure due to Tsallis relative entropy in order to measure the degree of entanglement. Then we study its properies with respect to the parameter q appearing in Tsallis entropies. In addition, the relation between it and the relative entropy of entanglement is studied.
