Moiré patterns in quantum images

J. A. O. Huguenin, M. P. Almeida, P. H. Souto Ribeiro +1

We observed moiré fringes in spatial quantum correlations between twin photons generated by parametric down-conversion. Spatially periodic structures were nonlocally superposed giv…

Experimental investigation of quantum key distribution with position and momentum of photon pairs

M. P. Almeida, S. P. Walborn, P. H. Souto Ribeiro

We investigate the utility of Einstein-Podolsky-Rosen correlations of the position and momentum of photon pairs from parametric down-conversion in the implementation of a secure qu…
