Finite-time measurement-driven Otto cycle

A novel quantum Otto heat engine that operates within a finite-time framework by incorporating measurement procedures is proposed. Departing from conventional quantum Otto heat engines, our model replaces the heat absorption process from a high-temperature source with invasive measurement. Moreover, we consider finite-time thermodynamic manipulation in each step. Our model focuses on exploring the effects of the angles of the measurement basis on the Bloch sphere and the timings of time-dependent evolutions on thermodynamic properties, with a specific emphasis on the trade-off between the power output and the efficiency. Our findings demonstrate that by carefully selecting specific parameters, the efficiency and overall performance of this heat engine can be significantly enhanced.
