My take: neat, but not as important as simply including a decent
hardware RNG (even a slow one) in all PC chipsets would be.
True.
The thing that bothers me about this description is the too-easy jump
between "chaotic" and "random". They're different concepts, and
chaotic doesn't imply random in a cryptographic sense: It may be
possible to induce bias or even some degree of predictability in a
chaotic system by manipulating its environment. I believe there are
also chaotic systems that are hard to predict in the forward
direction, but easy to run backwards, at least sometimes.
That's not to say this system isn't good - it probably is - but just
saying its chaotic shouldn't be enough.
BTW, a link from this article - at least when I looked at it - went to http://www.physorg.com/news147698804.html
: "Quantum Computing: Entanglement May Not Be Necessary". There are
still tons of surprises in the quantum computing arena....
