Multimode Hong-Ou-Mandel Interferometry
S. P. Walborn, W. A. T. Nogueira, A. N. de Oliveira +2
We review some recent experiments based upon multimode two-photon interference of photon pairs created by spontaneous parametric down-conversion. The new element provided by these…
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…
Conservation and entanglement of Hermite-Gaussian modes in parametric down-conversion
S. P. Walborn, S. Pádua, C. H. Monken
We show that the transfer of the angular spectrum of the pump beam to the two-photon state in spontaneous parametric down-conversion enables the generation of entangled Hermite-Gau…
