  We apply the quantum jump approach to address the statistics of work in a
driven two-level system coupled to a heat bath. We demonstrate how this
question can be analyzed by counting photons absorbed and emitted by the
environment in repeated experiments. We find that the common non-equilibrium
fluctuation relations are satisfied identically. The usual
fluctuation-dissipation theorem for linear response applies for weak
dissipation and/or weak drive. We point out qualitative differences between the
classical and quantum regimes.
