Some nice explanations of analysing the outputs

Speaker: Sean Boyce Security Researcher
The problem of generating "reasonable" approximations to random
numbers has been solved quite some time ago... but this talk is not
for reasonable people. Generating true random numbers with a
deterministic system is impossible; and so we must drink deeply from
the raw, godless chaos of quantum physics.
This talk will cover the various pitfalls of quantum true random
number generator construction, including bias, statistical relatedness
between bits, and unpleasant supply voltages. A working reference
design that overcomes these hurdles will be described, and barring
major disaster, demonstrated. Notably, this design contains a custom,
fully solid-state particle detector that may be constructed for around
USD 20$.
To benefit the most from this lecture, a very basic knowledge of
statistics, particle physics, and/or analog electronics is ideal;
however enough background will be provided that this will not be
strictly necessary. If in doubt, the Wikipedia articles on quantum
tunneling, alpha particle, normal distribution, operational amplifier,
and hardware random number generator should provide more than
sufficient background. Demo
