Experiments in the Quantum World

This session is devoted to presenting the state of the art in various experimental quantum systems, which have reached a sufficient level of control to eventually probe thermodynamics properties of quantum information. The goal of the session is twofold. First, it consists in giving theorists in quantum thermodynamics an overview of concrete experimental quantum systems with their advantages and drawbacks. Second, it invites experimentalists to think of how their systems may enlighten our understanding of quantum thermodynamics.

Thermodynamics and classical information

The purpose of this session is to provide an overview on classical information to energy  conversion protocols (Landauer erasure, Maxwell demons, Szilard engines), and fluctuation theorems in the classical regime.

Quantum equilibration

The scope of this session is twofold. On one hand, the way thermal quantum states, which are the basic building blocks of quantum statistical mechanics, arise from quantum dynamics in closed or quasiclosed systems will be explored. On the other hand, physical processes of relaxation of out-of-equilibrium systems exposed to the influences of an environment will be reviewed, with particular emphasis given to the experimental progress made in this line.

Classical and quantum trajectories

The evolution of a system in presence of classical or quantum noise can be represented as a random trajectory. Recent advances in the efficiency of detectors now allow to actually measure single realizations of trajectories. This session will present the most advanced results on these realizations and their statistics.

Quantum Engines

This session is devoted to implementations of nano-engines in a wide range of devices, from trapped ions to cold atoms or hybrid opto-mechanical systems. Protocols to optimize their efficiency and power will be reviewed, as well as the influence of the nature of the bath (finite, coherent, out of equilibrium). The case of engines working with a few entangled qubits is also relevant to the present session.

Quantum detectors of heat and work

One of the most pressing challenges for experiments to probe thermodyanmics quantities consists in efficiently measuring heat and work. This session will present detectors of quantum systems, which are/could be used to access work and heat.
