I recall that noise from a Zener diode is quantum mechanical and follows a well-known and well-defined theoretical spectrum (might it be the 1/f law?). As is well known, distributions can be transformed to obtain the desired one (exponential / Gaussian etc.). Combining the results by Santha and Vazira mentioned by Albert Boulanger with a quantum electrodynamical source of noise might even best a good pseudorandom number generator. Andy Ylikoski
