Traditional thermodynamics deals with macroscopic systems in thermal equilibrium, where one only has control over a few macroscopic variables (volume, temperature, etc).
This minimal level of control is in contrast with the great progress
over the last decades in the coherent control of single quantum systems.
Based on the notion of passive states, in this talk I will describe an
extension of the standard notions of thermodynamics (in particular the
problem of work extraction) for highly controllable small quantum
systems. Concretely, I will discuss how the maximal work extraction
principle is modified in the presence of entangling operations,
correlations, finite baths, and strong system-bath interactions.
