Applications of many-body non-equilibrium dynamics to quantum technologies

Resumo: Quantum technologies take advantage of properties developed by quantum systems when driven out of equilibrium. For example, quantum computation is based on an accurate, controlled driving of these systems to perform specific dynamics which produce entanglement, compute basic gates, and eventually leads to the completion of a numerical algorithm. Thermal fluctuations are often an enemy which spoils the controlled out-of-equilibrium dynamics.  On the other side, quantum thermodynamics takes advantage of thermal – and quantum – fluctuations to create engines and refrigerators of sizes well below the thermodynamic limit and properties still under discussion. In this talk I will first focus on engineering robust properties for distributed quantum computing using spin-networks [1]: here the twist
is {\it not} to drive the out-of-equilibrium dynamics, but let the system Hamiltonian do the job. I will then turn up the temperature, and consider a less-explored aspect of quantum thermodynamics, that is the effects and signatures of many-body interactions on few-electrons’
quantum machines [2].
