Abstract
Multipartite quantum correlation is one of the most relevant indicators of the quantumness of a system in many body systems. This remarkable feature is in general difficult to characterize and the known definitions are hard to measure. Besides the efforts dedicated to solve this problem, the question of which is the best approach remains open. In this paper, we study the global quantum discord (GQD) as a bipartite and multipartite measure. We also check the limits of this definition and present an experimental scheme to determine the maximum of the GQD via the measurements of the system's excitations, during the time evolution of the present system.
