Nonlocal quantum differentiation between polarization objects using entanglement
Vira R. Besaga, Luosha Zhang, Andres Vega +6
For a wide range of applications a fast, non-destructive, remote, and sensitive identification of samples with predefined characteristics is preferred instead of their full charact…
Experimental analysis on image resolution of quantum imaging with undetected light through position correlations
Marta Gilaberte Basset, René Sondenheimer, Jorge Fuenzalida +7
Image resolution of quantum imaging with undetected photons is governed by the spatial correlations existing between the photons of a photon pair that has been generated in a nonli…
Pinhole quantum ghost imaging
Andres Vega, Sina Saravi, Thomas Pertsch +1
We propose a quantum ghost imaging scheme based on biphotons, that, by using a collimated pump beam of the right size for biphoton generation, obviates the need for lenses to achie…
Sub-minute Quantum Ghost Imaging in the infrared enabled by a "looking back" SPAD array
Valerio Flavio Gili, Dupish Dupish, Andres Vega +6
Quantum Ghost Imaging (QGI) is an intriguing imaging protocol that exploits photon-pair correlations stemming from spontaneous parametric down-conversion (SPDC). QGI retrieves imag…
Fundamental resolution limit of quantum imaging with undetected photons
Andres Vega, Elkin A. Santos, Jorge Fuenzalida +5
Quantum imaging with undetected photons relies on the principle of induced coherence without induced emission and uses two sources of photon-pairs with a signal- and an idler photo…
Mid-Infrared Photon-Pair Generation in AgGaS
Mohit Kumar, Pawan Kumar, Andres Vega +3
We demonstrate non-degenerate photon-pair generation by spontaneous parametric down conversion in a silver gallium sulfide AgGaS crystal. By tuning the pump wavelength, we achi…
Metasurface-Assisted Quantum Ghost Discrimination of Polarization Objects
Andres Vega, Thomas Pertsch, Frank Setzpfandt +1
We develop a concept of metasurface-assisted ghost imaging for non-local discrimination between a set of polarization objects. The specially designed metasurfaces are incorporated…
