We are glad to announce the first seminar of the series on "Trieste Quantum". This series focuses on the scientific activities of the quantum field at the University of Trieste.
The first speaker of this series will be Prof. Fabio Anselmi from the Department of Mathematics, Informatics, and Geoscience. The seminar will be held on Monday, April 8, at 3:00 p.m. in Aula B1 at the H3 Building, via Valerio 12. In the following, you can find the title and abstract of this seminar:
Title: Controlling Quantum System Properties through Automatic Differentiation

Abstract: The so-called second quantum technological revolution is evolving at a rapid pace and promises significant impacts not only on science but also within the industrial sector.  Progress in this field critically relies on efficient methods for controlling the quantum properties of systems and their dynamics. In this talk we are going to give two illustrative examples of how, using a key algorithm in modern machine learning, automatic differentiation, we can control the properties of interest of a quantum system. Our initial case study focuses on the control of the tunneling probability of particles in a two-mode system. We show that when the quantum system is coupled to an ancilla, one can learn the optimal ancillary component and the optimal coupling, such that the tunneling probability/time can be controlled. The subsequent example addresses the mitigation of decoherence within a quantum system with noise. Employing a similar methodology, we show how we can learn an ancillary system and its corresponding noise parameters to counteract and diminish the impact of system noise.
