One more. When we say entropy and random numbers, we generally mean completely unpredictable. Intel's RDRAND, ekey, presumably ID-Quantique's solution and others rely for their entropy on quantum physics. If our understanding of quantum physics is correct, then by constructing such and such

If this is not your field of expertise the you should not call Intel's solution junk. It will not help with disks. What it helps with is applications that need properly independent random numbers often. A VPN server is such a case, it needs a few bits every time a client opens a connection

I found this seemingly cool product, a pci-e hardware RNG that produces a large stream of "truly random" "quantum" random numbers. https://www.idquantique.com/ It is made in Switzerland, which is cool as it isn't outsourced and it endeavors way more trust than chinese hardware. I am
