Abstract
A theory is presented for the photodetection statistics of radiation produced by current fluctuations in a phase-coherent conductor. Deviations are found from the Poisson statistics that would result from a classical current. For detection in a narrow frequency interval , the photocount distribution has the negative-binomial form of blackbody radiation if is less than the mean current in the conductor. When electronic localization sets in, drops below and a different type of super-Poissonian photon statistics results.
