Query: Cumulative measure of correlation for multipartite quantum states   The present article proposes a measure of correlation for multiqubit mixed
states. The measure is defined recursively, accumulating the correlation of the
subspaces, making it simple to calculate without using of regression. Unlike
usual measures, the proposed measure is continuous additive and reflects the
dimensionality of the state space, allowing to compare states with different
dimensions. Examples show that the measure can signal critical points (CP) in
the analysis of Quantum Phase Transitions in Heisenberg models.
