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…
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…
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…
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…
Diffraction of correlated biphotons through transparent samples
Nazanin Dehghan, Alessio D'Errico, Yingwen Zhang +2
Two-photon states generated through degenerate spontaneous parametric down-conversion (SPDC) can exhibit sharp correlations in the transverse spatial coordinates. This property lea…
Biphoton State Reconstruction via Phase Retrieval Methods
Nazanin Dehghan, Alessio D'Errico, Francesco Di Colandrea +1
The complete measurement of the quantum state of two correlated photons requires reconstructing the amplitude and phase of the biphoton wavefunction. We show how, by means of spati…
Manifestation of the Berry connection in chiral lattice systems
Francesco Di Colandrea, Nazanin Dehghan, Filippo Cardano +2
The Aharonov-Bohm effect is a physical phenomenon where the vector potential induces a phase shift of electron wavepackets in regions with zero magnetic fields. It is often referre…
Fourier Quantum Process Tomography
Francesco Di Colandrea, Nazanin Dehghan, Alessio D'Errico +1
The characterization of a quantum device is a crucial step in the development of quantum experiments. This is accomplished via Quantum Process Tomography, which combines the outcom…
Effect of Aberrations on 3D optical topologies
Nazanin Dehghan, Alessio D'Errico, Tareq Jaouni +1
Optical knots and links, consisting of trajectories of phase or polarisation singularities, are intriguing nontrivial three-dimensional topologies. They are theoretically predicted…
Interferometric imaging of amplitude and phase of spatial biphoton states
Danilo Zia, Nazanin Dehghan, Alessio D'Errico +2
High-dimensional biphoton states are promising resources for quantum applications, ranging from high-dimensional quantum communications to quantum imaging. A pivotal task is fully…
