Embodiment Construction
[0019] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:
[0020] The basic quantity of quantum mechanics is completely random due to its unpredictability, irregularity and non-repetition, so the true randomness shown in some aspects of the basic quantity of quantum mechanics can be used to generate true random numbers. As we all know, a coherent light source with a certain intensity has the characteristic of Poisson photon count statistics, and the detection of coherent light also conforms to the Poisson distribution. For example, if the light intensity is adjusted so that the average number of photons per pulse is 2, the number of photons detected each time is actually uncertain, and can be different values such as 0, 1, 2, 3, etc., but according to the Poisson distribution The princip...
