Abstract
We apply the Jaynes principle of maximum entropy for the partial recon struction of correlated spin states. We determine the minimum set of o bservables which is necessary for the complete reconstruction of the m ost correlated states of systems composed of spins 1/2 (e.g. the Bell and the Greenberger-Horne-Zeilinger states). We investigate to what ex tent an incomplete measurement can reveal non-classical features of co rrelated spin states.
