Quantum Discord and entropic measures of quantum correlations: Optimization and behavior in finite spin chains
N. Canosa, M. Cerezo, N. Gigena +1
We discuss a generalization of the conditional entropy and one-way information deficit in quantum systems, based on general entropic forms. The formalism allows to consider simple…

Bipartite entanglement in fermion systems
N. Gigena, R. Rossignoli
We discuss the relation between fermion entanglement and bipartite entanglement. We first show that an exact correspondence between them arises when the states are constrained to h…
