What bothers me, is the quote:

At the end of the metastable state, the contents of the memory are purely random. The researchers' experiments with an array of flip-flop units show that for small arrays the extra layer makes the random number almost twenty times more 'random' than conventional methods

If it's "purely" random (as they put it), then how can you measure the difference between it and a "conventional" method? Wouldn't comparing a pseudo random source to "true" randomness be like comparing a finite number to infinity? In that you "know" it's more random, but it's impossible to quantify with a finite value (the twenty times qualifier)?
