It is a central question in quantum thermodynamics to determine how irreversible is a process that transforms an initial state $\rho$ to a final state $\sigma$, and whether such irreversibility can be thought of as a useful resource. For example, we might ask how much work can be obtained by thermalizing $\rho$ to a thermal state $\sigma$ at temperature $T$ of an ambient heat bath. Here, we show that, for different sets of resource-theoretic thermodynamic operations, the amount of entropy… Expand

TLDR
This chapter shall see in this chapter that thermal interactions can be modelled as a resource theory, and the state transition conditions arising out of such a framework, are referred to as "second laws". Expand

Axiomatic Characterization of the Quantum Relative Entropy and Free Energy
TLDR
It is demonstrated that, under reasonable restrictions, the free energy is singled out as a measure of athermality as well as an extended class of Gibbs-preserving maps as free operations in a resource-theoretic framework. Expand

Stochastic Independence as a Resource in Small-Scale Thermodynamics.
TLDR
The many, severe constraints of microscopic thermodynamics are reduced to the sole requirement that the nonequilibrium free energy decreases in the transformation, which shows that, in principle, reliable extraction of work equal to the free energy of a system can be performed by microscopic engines.

Reversible Framework for Quantum Resource Theories.
TLDR
The general structure of QRTs is discussed, and it is shown that under a few assumptions, a QRT is asymptotically reversible if its set of allowed operations is maximal, that is, if the allowed operations are the set of all operations that do not generate (asymptotical) a resource. Expand

Resource theory of quantum states out of thermal equilibrium.
TLDR
It is shown that the free energy of thermodynamics emerges naturally from the resource theory of energy-preserving transformations, provided that a sublinear amount of coherent superposition over energy levels is available, a situation analogous to the sub linear amount of classical communication required for entanglement dilution. Expand
Coherence and measurement in quantum thermodynamics
TLDR
Information processing tasks, the so-called projections, that can only be formulated within the framework of quantum mechanics are identified and it is shown that the physical realisation of such projections can come with a non-trivial thermodynamic work only for quantum states with coherences.

TLDR
It is proved that the second law of thermodynamics holds in this framework, and a simple protocol is given to extract the optimal amount of work from the system, equal to its change in free energy. Expand

Quantum thermodynamics of general quantum processes.
TLDR
It is shown that heat, from the first law, is positive when the input state of the map majorizes the output state, and the change in entropy is also positive for the same majorization condition, making a strong connection between the two operational laws of thermodynamics. Expand
