Our setup brings out the need for a careful selection of the signal-idler photon pairs for our study of visibility and distinguishability. Indeed, when the signal photons interfering at the double-slit belong to this double-hump mode we obtain almost perfect visibility of the interference fringes and no \"which-slit\" information is available. However, when we break the symmetry between the two maxima of th","authors_text":"Axel Heuer, Dirk Puhlmann, Ralf Menzel, Robert Marx, Wolfgang P.
