Quantification of entanglement via uncertainties
Alexander A. Klyachko, Barış Öztop, A.S. Shumovsky · Physical Review A · 2007
We show that entanglement of pure multiparty states can be quantified by means of quantum uncertainties of certain basic observables through the use of a measure that was initially proposed by Klyachko et al. [Appl. Phys. Lett. 88, 124102 (2006)] for bipartite systems.
