Temporal limitations and digital data processing in continuous variable measurements of non-Gaussian states
Antoine Petitjean, Anthony Martin, Mohamed F. Melalkia +6
Non-Gaussian quantum states and operations are essential tools for multiple quantum information protocols exploiting light as information career. In this context, a key role is pla…
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…
Deployed quantum key distribution network: further, longer and more users
Nathan Lecaron, Yoann Pelet, Grégory Sauder +6
Entanglement-based quantum links are the backbone of future quantum internet networks, enabling secure communication between distant cities. Realizing such networks requires addres…
Self-referenced nonlinear interferometry for chromatic dispersion sensing across multiple length scales
Romain Dalidet, Sébastien Tanzilli, Gregory Sauder +2
Chromatic dispersion critically impacts the performance of numerous applications ranging from telecommunication links to ultrafast optics and nonlinear devices, yet fast and precis…
High-resolution broadband characterization of resonance dispersion in an optical microresonator
Romain Dalidet, Adrien Bensemhoun, Gregory Sauder +12
Accurate knowledge of the uneven free spectral range of an optical microresonator, which provides direct insight into group velocity dispersion, is essential for understanding and…
