This work reports the realization of energy-time and time-bin entangled photon-pair sources based on a periodically poled lithium niobate (PPLN) waveguide. Degenerate twin photons around 1314 nm wavelength are created by spontaneous parametric down-conversion and coupled into standard telecom fibers.The PPLN waveguide produces a conversion...

Applications of integrated and guided-wave optics to quantum sources, detectors, interfaces, memories and linear optical quantum com- puting are described in this review. By their inherent compactness, efficiencies, and interconnectability, many of the demonstrated individual devices can clearly serve as building blocks for more complex quantum...

Bohr's complementarity notion is at the heart of quantum physics. It suggests that quantum systems are observed as waves or particles depending on the type of measurement, i.e., the experimental arrangement, they are subjected to. For instance, sending single photons to an open or closed Mach-Zehnder interferometer (MZI) leads to the...

Le concept d'interférométrie quantique en lumière blanche est introduit et appliqué à la mesure de dispersion chromatique avec une précision inégalée.Dans cette présentation, nous introduirons d'abord le concept de l'interférométrie quantique en lumière blanche avec un état N00N à deux photons (N = 2). Nous montrerons que la phase optique peut...

Les guides optiques intégrés sur du niobate de lithium polarisé périodiquement (guides PPLN), associés aux composants télécoms standards, constituent aujourd'hui l'une des principales ressources technologiques pour les expériences de communication quantique fibrées. En effet, la structure guidante offre à la fois un bon couplage avec les fibres...
