The invention relates to a light source comprising a photonic wire having a single-mode core and adapted to support an optical mode which is degenerate in polarization, comprising an emitter of a pair of photons which are intended to be entangled in polarization. The photonic wire comprises a cladding which is asymmetrical in rotation and extends along a principal transverse axis. Furthermore, the light source comprises a correction device adapted to induce by electrostatic effect a mechanical deformation of the photonic wire in a plane parallel to the substrate, along a deformation axis forming an angle of inclination of between 0° and 90°, these values being exclusive, with respect to the principal transverse axis, the mechanical deformation leading to mechanical strains experienced by the emitter, thus improving the degree of entanglement of the photon pair.

Light source adapted to emit pairs of polarization-entangled photons

System for transporting objects under controlled atmosphere comprising tubular sections connected together in a leak tight manner by their first ends, each tubular section, each section comprising a guide track for a trolley, each guide track comprising a first and a second end, the first ends of the guide tracks being opposite and separated from each other by a given distance. The transport system also comprises a spanning element rotationally hinged on a first end of the guide tracks around an axis orthogonal to a direction of displacement of said guide track. The spanning element is moveable between a raised position and a spanning position in which the guide tracks are connected enabling the passage of the trolley.
