Abstract[English]
A quantum random number generator (QRNG) system including optocoupler including at least one light emitter and at least two light receivers that are electrically coupled to each other in a configuration that rejects common mode noise. The system also includes a controller configured to control the at least one light emitter to emit photons randomly towards the at least two light receivers, measure a shot noise signal generated by the at least two light receivers in response to receiving the photons, and extract a random number from the shot noise signal.[French]
L'invention concerne un système générateur de nombres aléatoires quantiques (QRNG) comprenant un optocoupleur comprenant au moins un émetteur de lumière et au moins deux récepteurs de lumière qui sont électriquement couplés l'un à l'autre dans une configuration qui rejette le bruit de mode commun. Le système comprend également un contrôleur configuré pour commander le ou les émetteurs de lumière pour émettre des photons aléatoirement vers lesdits au moins deux récepteurs de lumière, mesurer un signal de bruit de grenaille généré par lesdits au moins deux récepteurs de lumière en réponse à la réception des photons, et extraire un nombre aléatoire à partir du signal de bruit de grenaille.
