Abstract

We present here an overview of our work concerning entanglement
properties of composite quantum systems. The characterization of
entanglement, i.e. the possibility to assert if a given quantum state is
entangled with others and how much entangled it is, remains one of the
most fundamental open questions in quantum information theory. We
discuss our recent results related to the problem of separability and
distillability for distinguishable particles, employing the tool of
witness operators. Finally, we also state our results concerning quantum
correlations for indistinguishable particles.
