Abstract
The characteristics of a reciprocating quantum heat engine's limit cycle were analyzed. The proposed engine is based on a working medium consisting of an ensemble of quantum systems composed of two coupled spins. To prove the monotonic approach to limit cycle, the quantum conditional entropy was employed. It was observed that the phenomena of friction can be identified with a zero change in the von Neumann entropy of the working medium.
