    "abstract": "Quantum correlation, or entanglement, is now believed to be an indispensable\nphysical resource for certain tasks in quantum information processing, for\nwhich classically correlated states cannot be useful. Besides information\nprocessing, what kind of physical processes can exploit entanglement? In this\npaper, we show that there is indeed a more basic relationship between\nentanglement and its usefulness in thermodynamics. We derive an inequality\nshowing that we can extract more work out of a heat bath via entangled systems\nthan via classically correlated ones. We also analyze the work balance of the\nprocess as a heat engine, in connection with the Second Law of thermodynamics.",
