We investigate coherent transport through a driven two-level system with one level coupled to an electron source and the other to a drain. The current turns out to be significantly influenced by the ac driving. We focus on the regime of strong electron-electron interaction, in which Coulomb blockade is observed. The central quantities of interest are the average current and the Fano factor, where the latter is defined as the ratio between noise power and average current. This quantity provides information about the nature of the underlying transport process.
