Abstract
In this dissertation, we introduce the generalized global quantum discord, called the q-global quantum discord
(q-GQD), which is dened in terms of the quantum Tsallis entropy, and obtain the analytical expressions of q-GQD for
the special classe of multi-qubit states. Furthermore, we show a monogamy inequality for pairwise quantum correlation, which implies that the sum of pairwise quantum correlations is upper bounded by multipartite quantum correlation with respect to q-GQD.
