f(n) mod m is not necessarily (or even usually) periodic.
Anybody who pays real money for a black box
that is supposed to output random numbers through quantum theory
is very gullible, in my view.
It is one thing to understand quantum mechanics,
and quite another to construct a device that uses it.
You might as well say that if you understand thermodynamics
you can construct an efficient car engine.
Ps Do you know about quantum entanglement?
