主讲人简介

Roberto Serra is a Professor of Physics at the Federal University of ABC, UFABC (Brazil), where he previously served as Associate Dean for Graduate Studies. Before, he was a postdoctoral researcher at Imperial College London and a Newton Advanced Fellow of the Royal Society at the University of York (UK). His research focuses on Quantum Information Science, and he is recognized for pioneering experimental work in quantum thermodynamics (particularly in non-equilibrium scenarios) including the first laboratory verifications of quantum fluctuation theorems. His work aims the establishment of fundamental limits of energy efficiency for future quantum technologies.

讲座简介

Thermodynamics establishes important limits for different technologies, and this is no different for new quantum technologies 2.0 (such as: quantum computing, quantum sensors, etc.). In the latter case, non-equilibrium dynamics, energy fluctuations, and randomness are fundamentally present. On the other hand, modern techniques for manipulating quantum systems allow experimental access to microscopic states and degrees of freedom (at individual quantum level), highlighting the role of information theory in different protocols, which is introducing new perspectives for technological applications. Moreover, quantum characteristics such as coherence and non-classical correlations can be employed to obtain advantages or perform processes that would be impossible in the classical context. A general understanding of the thermodynamic limits in quantum technologies requires the development of new thermodynamic paradigms to generalize its laws in, not only, far-from-equilibrium situations, but also considering a scenario where access to microscopic states is possible, and to incorporate quantum characteristics such as coherence. Such a development has been called Quantum Thermodynamics. In this talk, we will discuss some direction in this recent development of Quantum Thermodynamics and its relationship with quantum technology. We will explore some poof of principle experiments where some quantum advantage is employed to to perform tasks that literally challenge the standard second law of thermodynamics. We will discuss some generalizations of the second law in these quantum contexts and possibilities for apparently “transcending classical limits”. We will also address the need for advances in the thermodynamic description of quantum systems and devices to achieve new advances in quantum technologies.
