Abstract

We propose a way to look for quantum states that violate the inequality of strong superadditivity of the entanglement of formation from states that violate the same inequality for the Rényi measure of entanglement. In this way, we will look for quantum channels with superadditivity classical capacities. We propose also to investigate multipartite entanglement starting from the concept of monogamy of entanglement and possible applications to physical phenomena. Furthermore, we intend to look for ways to observer directly the entanglement in multipartite quantum systems.
