We introduce a "microcanonical" measure (complying with the "generalcanonical principle") over the second moments of pure bosonic Gaussian statesunder an energy constraint. We determine the average fidelity for theteleportation of states distributed according to such a measure and compare itto a threshold obtained from a feasible classical strategy. Furthermore, weshow that, under the proposed measure, the distribution of the entanglementconcentrates around a finite value at the thermodynamical limit and, ingeneral, the typical entanglement of Gaussian states with maximal energy E isnot close to the maximum allowed by E.Comment: 4 pages + 1 figure (not included in journal version
