Claim:
1. Device for random number generation based on an optical process of quantum nature comprising: a light source emitting photons randomly, a light detector comprising a photon sensor adapted to absorb the randomly emitted photons, an amplifier for converting an electron signal received from the photon sensor into a voltage and amplifying the voltage signal, and an analog-to-digital converter (ADC) for treating the amplified signal received from the amplifier by encoding the amplified signal into digital values and sending these digital values to a randomness extractor of the device for further processing, wherein the randomness extractor is adapted to generate a number k of high-entropy output bits y the photon sensor of the light detector is adapted to operate in a linear regime and acts as a photon-to-electron converter to allow the light detector to be adapted to measure a number n of photons produced by said light source in a time interval T, the randomness extractor is adapted, for raw input bits r
