The question of whether quantum coherence is a resource beneficial or detrimental to the performance of quantum heat engines has been thoroughly studied but remains undecided. To isolate the contribution of coherence, we analyze the performance of a purely coherence-driven quantum heat engine, a device that does not include any heat flow during the thermodynamic cycle. The engine is powered by the coherence of a multiqubit system, where each qubit is charged via interaction with a coherence bath…

Work and Fluctuations: Coherent vs. Incoherent Ergotropy Extraction

We consider a quasi-probability distribution of work for an isolated quantum system coupled to the energy-storage device given by the ideal weight. Specif-ically, we analyze a trade-off between

Quantum Thermodynamics and Optomechanics

Thermodynamics was developed in the 19th century to study steam engines using the cyclical transformations of a working substance to extract heat from thermal baths and convert it into work, possibly

Extracting Work from a Single Heat Bath via Vanishing Quantum Coherence

We present here a quantum Carnot engine in which the atoms in the heat bath are given a small bit of quantum coherence. The induced quantum coherence becomes vanishingly small in the high-temperature
