Abstract (en)
[origin: WO2010062161A2] A method and apparatus (10) for generating random numbers using high-order grating (12) by wave diffraction of emitting photons from the grating (12) is disclosed. The apparatus (10) includes a particle source (11) capable of emitting a source of particles, a high-order grating (12) including output surfaces (22, 23), said high-order grating being disposed in relation to said particle source so that said source of particles encounter said high-order grating (12) for diffraction and particle which goes through constructive interference emits through either output surfaces (22, 23) of said grating (12), and at least one detector for capturing said emitted particle to a random signal to be processed for outputting a random number.
