The rapid advance of quantum information technology requires precise control and manipulation of quantum systems; in particular, it is essential to certify that quantum processors truly work quantum mechanically, in order to validate experiments and their results. The main problems adressed in this thesis concern finding optimal strategies for the estimation and characterization of quantum states and channels, with a special focus on entanglement correlations. We considered the certification of entanglement across a given partition of a multi-qubit system, when only partial information about the corresponding quantum state is available; we tackled the problem with an algorithm based on the truncated moment sequences (tms) problem, thus iden...
