Random, but not by chance: A new kind of random number generator

The article says that Newtonian physics does not allow any randomness, which is fairly obvious and has nothing to do with the hardware I'm asking about.

The article also discusses 'pseudo-random number generators', which, I'm assuming since this is HN, you know are purely software-based.

The Wikipedia page which I linked to, claims that currently used hardware uses 'thermal noise' and 'other quantum phenomena', which you might have realized "if you had bothered to read it".

If you don't mind now, I was really hoping to learn something about a technology which I am sincerely interested in.
