Quantum-enhanced phase interrogation of a fiber-optic strain sensor
Romain Dalidet, Marialuisa Capezzuto, Hugo Degert +7
Fiber-optic sensors enable high-sensitivity measurements of various physical parameters. Here, we demonstrate a quantum-enhanced interrogation of an all-fiber-optic Fabry-Perot res…
Robustness and optimization of N00N-state interferometry
Romain Dalidet, Anthony Martin, Louis Bellando +4
Quantum-enhanced interferometry is often discussed in terms of ideal resources and asymptotic scalings, whereas in practice its performance is set by a delicate interplay between l…
Quantum-enhanced sensing via spectral noise reduction
Romain Dalidet, Sébastien Tanzilli, Audrey Dot +4
We report a direct demonstration of quantum-enhanced sensing in the Fourier domain by comparing single- and two-photon interference in a fiber-based interferometer under strictly i…
High-brightness fiber-based Sagnac source of entangled photon pairs for multiplexed quantum networks
Tess Troisi, Yoann Pelet, Romain Dalidet +4
A fully fibered source of entangled photon pairs based on a nonlinear Sagnac interferometer is reported. Operating at telecom wavelengths, the source relies exclusively on standard…
