The interaction of coherent light with a single two level system (TLS) is one of the corner stones of quantum optics. In recent years experiments in this exciting field of quantum optics have been extended from atomic systems to semiconductor nanostructures, e.g. to the coherent control of self-assembled quantum dots (QDs). Here, we address the so far unexplored regime of resonance fluorescence in which the QD is excited not with a coherent laser, but with a narrowband chaotic light source. By analysing the resonantly scattered emission of the TLS, we find that the photon statistics of the excitation source greatly influences the TLS's dynamics in quantitative agreement with theoretical predictions.
