Recent work using tools from quantum information theory has shown that for small systems
where quantum e↵ects become prevalent, there is not one thermodynamical second law but many.
Derivations of these laws assume that an experimenter has very precise control of the system and
heat bath. Here we show that these multitude of laws can be saturated using two very simple
operations: changing the energy levels of the system and thermalizing over any two system energy
levels. Using these two operations, one can distill the optimal amount of work from a system, as
well as perform the reverse formation process. What is more, using only these two operations and
one ancilla qubit in a thermal state, one can transform any state into any other state allowable by
the second laws. We thus have the result that the second laws hold for fine-grained manipulation
of system and bath, but can be achieved using very coarse control. This brings the full array of
thermal operations towards a regime accessible by experiment, and establishes the physical relevance
of these second laws, potentially opening a new direction of studies. |
