A class of inequalities inducing new separability criteria for bipartite quantum systems
Paolo Aniello, Cosmo Lupo · Journal of Physics A Mathematical and Theoretical · 2008
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 inequalities satisfied by all separable states of a bipartite quantum system is derived. These inequalities induce new separability criteria that generalize the realignment criterion.
