Abstract
We investigate the use of a spatially distributed beam of entangled photons for applications of wavefront division interferometry. Using a fiber-based spontaneous parametric down conversion process, which redirect the signal and idler into a common single-mode fiber, we generate a Gaussian beam of colinear entangled photons randomly distributed in space. Coincidence measurements carried by wavefront division demonstrate quantum interference patterns, including classical single photon fringes, two-photon interferences and the Hong-Ou-Mandel effect. Our results are relevant for detecting transverse variations in the statistical properties of weak turbulence.
