Title:
DEVICE AND METHOD FOR GENERATING RANDOM NUMBER
Document Type and Number:
WIPO Patent Application WO/2018/068326
Kind Code:
A1
Abstract:
A device and method for generating a random number, capable of generating a true random number on the basis of intrinsic uncertainty of quantum mechanics. The device comprises: an electron pair generator (110) used for generating a first electron pair that comprises two electrons having opposite spin directions and the same migration direction; an electron pair separator (120) used for separating the first electron pair to obtain two independent electrons, the spin directions of the two independent electrons being opposite and the migration directions being independent from each other; and a random number generator (130) used for receiving a first input electron output by the electron pair separator (120), and generating a random number according to the spin direction of the first input electron that is either of the two independent electrons.
