Bipartite quantum systems: on the realignment criterion and beyond
Cosmo Lupo, Paolo Aniello, Antonello Scardicchio
Inspired by the `computable cross norm' or `realignment' criterion, we propose a new point of view about the characterization of the states of bipartite quantum systems. We conside…
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…

Partial scaling transform of multiqubit states as a criterion of separability
C. Lupo, V. Man'ko, G. Marmo +1
The partial scaling transform of the density matrix for multiqubit states is introduced to detect entanglement of quantum states. The transform contains partial transposition as a…
