Quantum mechanics teaches us that, at the deepest level, uncertainty
rules the universe: there are things we cannot predict, even in
principle. HotBits harnesses this fundamental
uncertainty of nature to generate truly random bits, unlike the
pseudorandom sequences created by an algorithm on a computer.
Along the way, you'll find a discussion of the hardware and
software used to generate the random bytes comprehensive enough
to build your own, and peek under the hood
of quantum mechanics to see why the data are genuinely random,
and some of the implications of all this.
