Resumen
We optimize one-qubit Novikov quantum heat engines with a dissipative heat leak using the formalisms of open-system Quantum Mechanics and the Finite-Time Thermodynamics. We show that the leak changes the power-efficiency and the efficient-power-efficiency curves, reduces the maximum efficiency of the machine and does not change its power. We also discuss the effects of the leak on the power that is rejected from the machine to the environment. Finally, we study the high-temperature limit to check that the engine reduces in this limit to a classic Novikov heat engine.
