Abstract

Work extractable from quantum systems can be viewed as a resource to perform some tasks. Here, we try to relate the work extractable to some resource theory. To do this, we consider completely passive states and passive states as free states and, by identifying the free operations, formulate resource theories where the maximum work extractable is a monotone. In particular, we study how the free operations act on the free states, showing how a sort of temperature plays a pivotal role in these resource theories.
