    "abstract": "With a class of quantum heat engines which consists of two-energy-eigenstate\nsystems undergoing, respectively, quantum adiabatic processes and energy\nexchanges with heat baths at different stages of a cycle, we are able to\nclarify some important aspects of the second law of thermodynamics. The quantum\nheat engines also offer a practical way, as an alternative to Szilard\u0027s engine,\nto physically realise Maxwell\u0027s daemon. While respecting the second law on the\naverage, they are also capable of extracting more work from the heat baths than\nis otherwise possible in thermal equilibrium.",
