Contrast enhanced imaging through weakly scattering media with spatially entangled photons

Alessio D'Errico, James Hubble, Rojan Abolhassani +4

Improving the image contrast of objects immersed in weakly scattering media can be achieved using various strategies. One common approach is to reject events associated with scatte…

Imaging Walk-Off Driven Distortions in EPR Photon Pair Correlations

Christian Howard, Roohollah Ghobadi, Nazanin Dehghan +2

Spontaneous parametric down-conversion is the primary source of position-correlated and momentum-anticorrelated photon pairs that form the canonical Einstein-Podolsky-Rosen (EPR) s…
