- Title: Correlation-boosted quantum engine: A proof-of-principle demonstration
- Authors: Marcela Herrera, John H. Reina, Irene D'Amico, Roberto M. Serra
- Abstract summary: We design and implement a non-classically correlated SWAP heat engine that allows to achieve an efficiency above the standard Carnot limit.
The boosted efficiency arises from a trade-off between the entropy production and the consumption of quantum correlations.
We implement a proof-of-principle demonstration of the engine efficiency enhancement by effectively tailoring the thermal engine on a cloud quantum processor.

- Abstract: Employing currently available quantum technology, we design and implement a
non-classically correlated SWAP heat engine that allows to achieve an
efficiency above the standard Carnot limit. Such an engine also boosts the
amount of extractable work, in a wider parameter window, with respect to
engine's cycle in the absence of initial quantum correlations in the working
substance. The boosted efficiency arises from a trade-off between the entropy
production and the consumption of quantum correlations during the full
thermodynamic cycle. We derive a generalized second-law limit for the
correlated cycle and implement a proof-of-principle demonstration of the engine
efficiency enhancement by effectively tailoring the thermal engine on a cloud
quantum processor.
