Quantum-Enhanced Heat Engine Based on Superabsorption

Abstract

We propose a quantum-enhanced heat engine with entanglement. The key feature of our scheme is superabsorption, which facilitates enhanced energy absorption by entangled qubits. Whereas a conventional engine with $N$ separable qubits provides power with a scaling of $P=\Theta (N)$, our engine uses superabsorption to provide power with a quantum scaling of $P=\Theta (N^2)$. This quantum heat engine also exhibits a scaling advantage over classical ones composed of $N$-particle Langevin systems. Our work elucidates the quantum properties allowing for the enhancement of performance.
