Patent ID: 6986056

Claim:
A method of generating a binary sequence of random numbers based on random selection of a path of photons on a beam splitter, the method comprising: emitting photons or photon swarms according to a randomness principle using a photon source, the photon source including a low power light source; splitting the photons or photon swarms emitted by the photon source during a measurement period using at least a first beam splitter and a second beam splitter disposed in a beam path of the light source, the second beam splitter being disposed downstream of the first beam splitter in a first downstream path of the first beam splitter; detecting, in accordance with the splitting, the photons of photon swarms from the splitting using a first, a second and a third detector connected to a detection device, the first detector being disposed in a second downstream path of the first beam splitter, the second detector being disposed in a third downstream path of the second beam splitter, the third detector being disposed in a fourth downstream path of the second beam splitter; generating a random number when the photons or photon swarms detected at the first, second and third detectors together correspond to a predefined photon scheme, and photon scheme including generating a random number when only one of the second and third detectors registers a detection of the photons of photon swarms.
