Entropy production is a key quantity in any finite-time thermodynamic process. It is intimately
tied with the fundamental laws of thermodynamics, embodying a tool to extend …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Recent studies have developed fundamental limitations on nanoscale thermodynamics, in
terms of a set of independent free energy relations. Here we show that free energy relations …

In this tutorial, we present the definition, interpretation, and properties of some of the main
quasiprobabilities that can describe the statistics of measurement outcomes evaluated at …

Heat spontaneously flows from hot to cold in standard thermodynamics. However, the latter
theory presupposes the absence of initial correlations between interacting systems. We here …

Landauer's erasure principle exposes an intrinsic relation between thermodynamics and
information theory: the erasure of information stored in a system, S, requires an amount of …

Although classical thermal machines power industries and modern living, quantum thermal
engines have yet to prove their utility. Here, we demonstrate a useful quantum absorption …

We analyze the production of entropy along nonequilibrium processes in quantum systems
coupled to generic environments. First, we show that the entropy production due to final …

There are several mathematical formulations of quantum mechanics. The Schrödinger
picture expresses quantum states in terms of wavefunctions over, eg position or momentum …

What does it mean for one quantum process to be more disordered than another?
Interestingly, this apparently abstract question arises naturally in a wide range of areas such …
