Modeling and benchmarking quantum optical neurons for efficient neural computation
Andrea Andrisani, Gennaro Vessio, Fabrizio Sgobba +3
Quantum optical neurons (QONs) are emerging as promising computational units that leverage photonic interference to perform neural operations in an energy-efficient and physically…
Momentum-resolved two photon interference of weak coherent states
Fabrizio Sgobba, Francesco Di Lena, Danilo Triggiani +7
We demonstrate an experimental scheme for high-precision position measurements based on transverse-momentum-resolved two-photon interferometry with independent photons and single p…
High-Precision Measurement of Time Delay with Frequency-Resolved Hong-Ou-Mandel Interference of Weak Coherent States
Francesco Di Lena, Fabrizio Sgobba, Danilo Triggiani +7
We demonstrate a scheme for high-precision measurements of time delay based on frequency-resolved Hong-Ou-Mandel (HOM) interference. Our approach is applied to weak coherent states…
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…
