Achieving quantum-limited sub-Rayleigh identification of incoherent sources with arbitrary intensities
Danilo Triggiani, Cosmo Lupo
The Rayleigh diffraction limit imposes a fundamental restriction on the resolution of direct imaging systems, hindering the identification of incoherent optical sources, such as ce…

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…
