Abstract
The performance of quantum heat engines is generally based on the analysis of a single cycle. We challenge this approach by showing that the total work performed by a quantum engine need not be proportional to the number of cycles. Furthermore, optimizing the engine over multiple cycles leads to the identification of scenarios with a quantum enhancement.We demonstrate our findings with a quantum Otto engine based on a two-level system as the working substance that supplies power to an external oscillator. © 2017 American Physical Society
