I think we should go quantum.
Take a really low intensity light source, stop it down to a single photon
and put it through a mirror with 50% transmission with detectors for both
transmission and reflection.
To remove bias from the mirror, read pairs of bits and reject them if they
are the same and take the first bit as the output bit otherwise.
There is a literature on this stuff.
