From the viewpoint of investigating the efficient use of heat by means of quantum resources, quantum heat engines, which are quantum extensions of heat engines, have attracted much attention. In the absorption and emission processes of heat, conventional studies have used the Markov approximation, but we describe these processes as a non-Markovian dynamics. As a result, we find that the quantum Otto cycle behaves differently from the conventional quantum heat engine because the interaction energy between a macroscopic heat bath and a microscopic qubit is not negligible [1]. This result demonstrates a unique feature of the quantum heat engine.
