Experimental subdiffraction source discrimination enabled by spatial demultiplexing and single-photon detectors
Luigi Santamaria Amato, Danilo Triggiani, Cosmo Lupo
We experimentally demonstrate a universal, parameter-independent test for asymmetric source discrimination. The test allows us to discriminate faint sources well beyond the diffrac…

Single-photon super-resolved spectroscopy from spatial-mode demultiplexing
Luigi Santamaria Amato, Fabrizio Sgobba, Deborah Pallotti +1
We demonstrate spectroscopy of incoherent light with sub-diffraction resolution. In a proof-of-principle experiment we analyze the spectrum of a pair of incoherent point-like sourc…

Engineering quantum states from a spatially structured quantum eraser
Carlo Schiano, Bereneice Sephton, Roberto Aiello +8
Quantum interference is a central resource in many quantum-enhanced tasks, from computation to communication protocols. While it usually occurs between identical input photons, qua…
