Factorization of quantum charge transport for noninteracting fermions

We show that the statistics of the charge transfer of noninteracting fermions through a two-lead contact is generalized binomial at any temperature and for any form of the scattering matrix: an arbitrary charge-transfer process can be decomposed into independent single-particle events. This result generalizes previous studies of adiabatic pumping at zero temperature and of transport induced by bias voltage.
