    "abstract": "We report an experiment to generate maximally entangled states of\nD-dimensional quantum systems, qudits, by using transverse spatial correlations\nof two parametric down-converted photons. Apertures with D-slits in the arms of\nthe twin fotons define the qudit space. By manipulating the pump beam correctly\nthe twin photons will pass only by symmetrically opposite slits, generating\nentangled states between these differents paths. Experimental results for\nqudits with D=4 and D=8 are shown. We demonstrate that the generated states are\nentangled states.",
