A class of inequalities inducing new separability criteria for bipartite quantum systems
Paolo Aniello, Cosmo Lupo
Inspired by the realignment or computable cross norm criterion, we present a new result about the characterization of quantum entanglement. Precisely, an interesting class of inequ…

Qubit-portraits of qudit states and quantum correlations
C. Lupo, V. I. Man'ko, G. Marmo
The machinery of qubit-portraits of qudit states, recently presented, is consider here in more details in order to characterize the presence of quantum correlations in bipartite qu…
