Abstract: An experimental setup is presented in which the ghost diffraction phenomenon can be observed for two un-entangled photons in the same mode. No quantum non-locality is involved in this case, because the photons are not spatially separated. Therefore the ghost diffraction phenomenon is not an experimental evidence for quantum non-locality.
