ABSTRACT

We show experimentally that quantum coincidence imaging with photon pairs generated by spontaneous
parametric down conversion, in certain conditions, differs from the classical imaging in two aspects: the
magnified image is produced by an “apodized” effective lens and its effective wavelength is the De Broglie
wavelength of the photon pair /2, where  is the central wavelength of the single photon wave packet. Better
resolution and apodization effects reduced intensity of the diffraction fringes around the image are observed
in the detected images.
