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…
Single-Image Entanglement Verification with Spatially Encoded Measurement Contexts
Nazanin Dehghan, Alessio D'Errico, Yingwen Zhang +3
Entangled photon pairs produced by spontaneous parametric down-conversion exhibit rich spatial entanglement structure that is often difficult to probe with conventional measurement…
Three-fold coincidence by stimulated parametric down-conversion
Yishai Klein, Alessio D'Errico, Farid Ghobadi +4
Parametric down-conversion is a widely used source of nonclassical light in quantum optics and photonic quantum technologies. While stimulated parametric down-conversion with stron…
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…
Compact and programmable large-scale optical processor in free space
Maria Gorizia Ammendola, Nazanin Dehghan, Lukas Scarfe +4
Photonic circuits are central to classical and quantum information processing. While integrated technologies dominate, free-space architectures are emerging as attractive alternati…
Programmable photonic quantum walks on lattices with cyclic, toroidal, and cylindrical topology
Alessio D'Errico, Nazanin Dehghan, Maria Gorizia Ammendola +5
Photonic implementations of unitary processes on lattice structures, such as quantum walks, have been demonstrated across various architectures. However, few platforms offer the co…
