Within the last decades fluctuation relations[1-4] have been established. Recent experiments have shown the validity of such fluctuation relations for entropy production in the microscopic regime[5]. However the extension of fluctuation relations of heat and work to the quantum regime is still under discussion, since non-ambiguous definitions for heat and work have not yet been established. In this context we consider the statistics of energy emitted by a driven two level system into a bosonic bath using the full counting statistics technique.
