Fast random number generator from vacuum "noise"
Canadian physicist Ben Sussman and his colleagues designed an extremely fast and constructively simple random number generator based on vacuum field fluctuations.
The universe is designed in such a way that at every point in space there are constantly emerging virtual particles with considerable energy. On a quantum scale, a vacuum is a wildly active, “living” substrate, where particles are born and annihilate, giving a total of zero. Although these particles are abstract objects of quantum field theory, they manifest themselves in specific physical processes, for example, the Casimir effect — the mutual attraction of conducting uncharged bodies. And here we have found another useful application of vacuum "noise" - the generation of random numbers.
The Sassman design consists of a pulsed high-frequency laser, a medium with a high refractive index (diamond), and a detector. Passing through a diamond, each pulse on the detector shows different characteristics, depending on the vacuum fluctuations of the field, which are encountered along the path of the photons. In the spectrum of the scattered radiation, spectral lines appear at the output that are not in the spectrum of the primary light (see Raman effect ), and because of the unpredictability of vacuum fluctuations, these lines each time differ in an unpredictable way. Due to the high intensity of laser radiation, fast detectors can be used, rather than single photon detectors.
Note that humanity does not even have a theoretical possibility to develop an apparatus for predicting zero-point oscillations, because by their nature they cannot be predicted. According to one theory, our Universe could have arisen from such a vacuum fluctuation that gave rise to a “bubble”. Moreover, at each time point in the vacuum, millions of such “universes” are constantly being born and dying - they can be used for RNG.
