Our Research Group belongs to Departamento de Física Fundamental at Universidad de Salamanca.

We study fundamental properties of quantum systems to set the foundations underpinning the development of future quantum technologies. Using high-performance numerical simulations and analytical techniques, we investigate questions such as the complexity of quantum states, the emergence of quantum chaos, dynamics of many-body systems, the role of many-particle interference effects, and the design of quantum computing platforms.
