Global thermal entanglement in n-qubit systems
R. Rossignoli, N. Canosa
We examine the entanglement of thermal states of n spins interacting through different types of XY couplings in the presence of a magnetic field, by evaluating the negativities of…

Generalized conditional entropy in bipartite quantum systems
N. Gigena, R. Rossignoli
We analyze, for a general concave entropic form, the associated conditional entropy of a quantum system A+B, obtained as a result of a local measurement on one of the systems (B).…
