AB  - The interplay between quantum-mechanical properties, such as coherence,and classical notions, such as energy, is a subtle topic at the forefront of quantumthermodynamics. The traditional Carnot argument limits the conversion of heat towork; here we critically assess the problem of converting coherence to work. Through acareful account of all resources involved in the thermodynamic transformations withina fully quantum-mechanical treatment, we show that there exist thermal machinesextracting work from coherence arbitrarily well. Such machines only need to act onindividual copies of a state and can be reused. On the other hand, we show thatfor any thermal machine with finite resources not all the coherence of a state can beextracted as work. However, even bounded thermal machines can be reused infinitelymany times in the process of work extraction from coherence.
