In order to describe quantum heat engines, here we systematically study isothermal and isochoric processes for quantum thermodynamic cycles. Based on these results the quantum versions of both the Carnot heat engine and the Otto heat engine are defined without ambiguities. We also study the properties of quantum Carnot and Otto heat engines in comparison with their classical counterparts. Relations and mappings between these two quantum heat engines are also investigated by considering their respective quantum thermodynamic processes. In addition, we discuss the role of Maxwell's demon in quantum thermodynamic cycles. We find that there is no violation of the second law, even in the existence of such a demon, when the demon is included correctly as part of the working substance of the heat engine.

Quantum Thermodynamics: A Dynamical Viewpoint (2013, background): “A reciprocating cycle is partitioned typically into four segments, two adiabats, where the working system is isolated from the environment, and two heat transfer segments, either isotherms for the Carnot cycle [12–17] or isochores for the Otto cycle [18–31].”
