Abstract[English]
A system comprises an optical circuit and a controller. The optical circuit comprises (i) a photon source to produce a photon sequence, (ii) a configurable interferometer to interfere photons of the photon sequence to produce an interfered photon sequence, the interferometer comprising first and second temporal mode coupling devices, (iii) a phase shifter configured to adjust a relative phase between the first temporal mode coupling device and the second temporal mode coupling device of the interferometer; and (iv) a detector arrangement comprising one or more photodetectors and configured to measure the interfered photon sequence. The controller is configured to obtain measurements of the interfered photon sequence; determine, from the obtained measurements, a relative phase between the first temporal mode coupling device and the second temporal mode coupling device; and based on the determined relative phase, controlling the phase shifter to adjust the relative phase.[French]
L'invention concerne un système comprenant un circuit optique et un dispositif de commande. Le circuit optique comprend (i) une source de photons pour produire une séquence de photons, (ii) un interféromètre configurable pour faire interférer des photons de la séquence de photons pour produire une séquence de photons ayant subi une interférence, l'interféromètre comprenant des premier et second dispositifs de couplage de mode temporel, (iii) un déphaseur configuré pour ajuster une phase relative entre le premier dispositif de couplage de mode temporel et le second dispositif de couplage de mode temporel de l'interféromètre; et (iv) un agencement de détecteur comprenant un ou plusieurs photodétecteurs et configuré pour mesurer la séquence de photons ayant subi une interférence. Le dispositif de commande est configuré pour obtenir des mesures de la séquence de photons ayant subi une interférence; déterminer, à partir des mesures obtenues, une phase relative entre le premier dispositif de couplage de mode temporel et le second dispositif de couplage de mode temporel; et sur la base de la phase relative déterminée, commander le déphaseur pour ajuster la phase relative.
