Dual wavelength source of entanglement for space quantum communication
Valentin Dumas, Alek Lagarrigue, Tess Troisi +4
We report the demonstration of a bulk, intrinsically phase-stable source of polarization- and time-energy-entangled photon pairs at 810nm and 1550nm, directly coupled into single-m…

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 phase sensitivity in an all-fiber Mach-Zehnder interferometer
Romain Dalidet, Sébastien Tanzilli, Gregory Sauder +3
Recent advances in quantum photonics have enabled increasingly robust protocols in optical phase estimation, achieving precisions beyond the standard quantum limit and approaching…
