Comparison between the theoretical and the experimental (resulting from the optical implementation of the protocol of Fig. 2) versions of density matrices for the three characteristic examples of states to be teleported, i.e., for: (a) \(\vert 0 \rangle \) theoretical, (b) \(\vert 0 \rangle \) experimental, (c) \(\vert 1 \rangle \) theoretical, (d) \(\vert 1 \rangle \) experimental, (e) \(\vert + \rangle \) theoretical, and (f) \(\vert + \rangle \) Experimental. The theoretical and experimental results of teleporting the \(\vert - \rangle \) state are not shown so as not to overload the figure. The most notable difference between both versions of the first two cases lies in the existence of non-zero values close to the correct elements, i.e., to those values close to the corners
