Quantum-limited optical delay sensing across an enhanced dynamic range by frequency-resolving two-photon interference
Russell M. J. Brooks, Luca Maggio, Thomas Jaeken +4
Optical sensing schemes that rely on two-photon interference provide a powerful platform for precision metrology, although they are inherently constrained by a trade-off between dy…

Quantum Interference of Distinguishable Photons Based on Spatially-Resolved Measurements
Miguel Angel Gonzalez, Alejandra Alarcón, Andres Camilo Quintero +5
We present experimental results demonstrating the quantum interference of two photons distinguishable in their transverse momenta, each entering the input ports of a balanced beam…

Quantum-limited estimation of the frequency shift between two interfering photons by time sampling of their quantum beats
Luca Maggio, Danilo Triggiani, Paolo Facchi +1
We present a sensing scheme for estimating the frequency difference of two non-entangled photons. The technique consists of time-resolving sampling measurements at the output of a…
