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…

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…
