  We study the effects of the generalized uncertainty principle (GUP) on the
efficiency of quantum heat engines based on a particle in an infinite square
well using the partition function approach. In particular, we study the Carnot
and Otto heat engines. For the system we used, the GUP-corrected efficiencies
turned out to be lower than efficiencies without the GUP effects. However, as
expected, GUP effects increase as the temperature of the cold heat bath
decreases and as the width of the potential well decreases.
