Abstract :
An exact knowledge and the possiblity of manipulating the spatial correlations of multi photon objects are of great interest for a number of applications in metrology and imaging. Since Fock-states of N-photons of wavelength lambda propagate through phase shifts N-times faster as coherent states they can appear as if they had a de Broglie wavelength of lambda/N. This has been studied for diffraction at ordinary gratings in.
