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…
An all-fibred, telecom technology compatible, room temperature, single-photon source
Nathan Lecaron, Max Meunier, Grégory Sauder +5
Single photon sources are essential building blocks for fundamental quantum optics but also for quantum information networks. Their widespread is currently hindered by unpractical…
Entanglement-based clock syntonization for quantum key distribution networks. Demonstration over a 50 km-long link
Yoann Pelet, Grégory Sauder, Sébastien Tanzilli +2
We present the implementation of a time synchronization protocol as part of an experimentally deployed entanglement-based quantum key distribution (QKD) link. The system is deploye…
