Abstract

Thermodynamics has played essential rule to the development of machines and technological devices. Most of the major advances have been proposed under the classical mechanics at a macroscopic scale. Considering the recent and growing ability to control and manipulate devices in nano-scales at a quantum regime, it is interesting to wonder about the limitations of thermodynamics in these contexts. The idea of extrapolating the concepts of thermodynamics to the quantum realm, beyond the equilibrium paradigm, has attracted much attention, particularly due to the great impact that it could have on the development of new technologies including information processing. This is a fairly recent trend with a just a few results up to now. The present project is developed in such a context. We intend to investigate various aspects involving non-equilibrium thermodynamics and quantum information. Among other objectives we will investigate the production of the so-called super-adiabatic evolutions (shortcuts adiabatic evolution), its thermodynamic costs, and we will employ this kind of evolutions to build a quantum heat engine. We will also study a general regime of operation of a quantum machine in the presence of quantum memory. All of our investigations will be performed from the quantum information science point of view. In parallel we will work in experimental implementations of these proposals in the context of Nuclear Magnetic Resonance. (AU)
