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