Superresolution imaging of two incoherent sources via two-photon interference sampling measurements in the transverse momenta
Salvatore Muratore, Danilo Triggiani, Vincenzo Tamma
The Rayleigh's criterion infamously imposes a minimum separation between two incoherent sources for them to be distinguishable via classical methods. In this work, we demonstrate t…

Multi-parameter estimation of the state of two interfering photonic qubits
L. Maggio, D. Triggiani, P. Facchi +1
It is demonstrated a two-photon interfering technique based on polarization-resolved measurements for the simultaneous estimation with the maximum sensitivity achievable in nature…

Estimation with ultimate quantum precision of the transverse displacement between two photons via two-photon interference sampling measurements
Danilo Triggiani, Vincenzo Tamma
We present a quantum sensing scheme achieving the ultimate quantum sensitivity in the estimation of the transverse displacement between two photons interfering at a balanced beam s…
