The present invention concerns a device for random number generation based on an optical process of quantum nature comprising a light source (1) emitting photons randomly times, the device further comprising a light detector (2) adapted to absorb the randomly emitted photons and to measure a number n of photons produced by said light source (1) in a time interval T, and a randomness extractor (3), wherein the detector (2) comprises a photon sensor (2.2) acting as a photon-to-electron converter, an amplifier (2.3) for converting the electron signal received from the photon sensor (2.2) into a voltage and amplifying the voltage signal (V), as well as an analogue-to-digital converter (ADC/2.4) for treating the amplified signal (V) received from the amplifier (2.3) by encoding the amplified signal (V) into digital values (d) and sending these digital values (d) to the randomness extractor (3) for further processing such as to produce quantum random numbers (QRNs) based on said number n of photons produced by the light source (1) in a time interval T. The invention is also related to a corresponding method and computer program means. |
