Anyone know a cheap DIY way to generate quantum-random numbers at home? For example, get a Geiger counter and wire it up to code that counts the milliseconds between clicks... something like that?
- BenjiWiebe 9y agoWouldn't a simple noise generator using a reverse-biased diode wired to an ADC be pretty good?
- smaddox 9y agoYes: use your chip's generator through your OS's random number generator (urandom on Linux). The chip's thermal-noise entropy source is fundamentally based on quantum mechanics.
