| The present article proposes a measure of correlation for multiqubit mixed states. The measure is de?ned recursively, accumulating the correlation of the subspaces, making it simple to calculate without the use of regression. Unlike usual measures, the proposed measure is continuous additive and re?ects the dimensionality of the state space, allowing to compare states with di?erent dimensions. Examples show that the measure can signal critical points (CPs) in the analysis of Quantum Phase Transitions (QPTs) in Heisenberg models. | |
