How much entropy is lost due to collision?
If entropy is hashed with SHA-256 for example, and the input has exactly 256 entropy bits, how much is entropy reduced after hashing due to collision?
Shannon entropy is then reduced by $\eta=0....

How much entropy is lost due to collision?
Let's assume that we have a uniform distribution. This is certainly not a given, but usually we assume that hash functions will try and have each output value be equally likely.
In that case we can ...

Entropy extraction from a Zener diode TRNG
An excellent idea.
The complete design of a Zener TRNG is quite lengthy, so I'll just list a set of points and include a link to the details. You could do worse than starting with the following which ...
