Teleporting images across a network securely using only light

"2 entangled photons (not needing more) sending 1 to receiver, who overlaps it on nonlinear detector with information that is to be sent not physically, so secure, while quantum link connecting parties is established by exchange of such photons... nonlinear 15 dimensional (scalable for more) secure channel optical fiber quantum network not strictly teleportation (for now) between 2 parties, provided protocol does not need to be fed with single photons, as would be case for quantum repeaters... picture, unique fingerprint, face"
