I definitely appreciate now that there are good algorithms to make your random bits more random, and hash functions can help, but regarding calling johnson nois

I definitely appreciate now that there are good algorithms to make your random bits more random, and hash functions can help, but regarding calling johnson noise quantum mechanical: can you give one reference of a description of finite-temperature johnson noise in which at least 1 observable necessitates a quantum mechanical treatment? (I don't think it exists, given that it is a thermal phenomenon, but maybe I'm wrong...)
