Quantum jump approach for work and dissipation in a two-level system

Understand

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.
