Shedding light on hidden properties of quantum many-body systems

Our research is geared towards leveraging the potentials of quantum matter with the aim of developing novel quantum technologies such as quantum simulation, quantum computation, and quantum metrology.

We perform theoretical studies based on analytical and numerical methods, as well as develop proposals for realizing and characterizing phase diagrams and non-equilibrium dynamics of quantum many-body systems.

These proposals draw on the astonishing abilities of quantum devices, e.g., based on ultracold quantum gases, trapped ions, or superconducting qubits, which are now reaching a level of precision and control that has been unimaginable just a few decades ago.

# Affiliations

Our group is embedded in the Pitaevskii BEC Center — a joint interinstitutional effort between CNR-INO and the University of Trento, bringing together theorists and experimentalists with the aim of gaining a deeper understanding of the physics related to Bose–Einstein condensation as well as achieving precise experimental control over ultracold atomic systems.

Moreover, we are part of Q@TN — Quantum Science and Technology in Trento — an interdisciplinary organization bringing together Physicists, Computer Scientists, Mathematicians, Material Scientists, and Engineers to advance the development of quantum technologies.

We are members of INFN-TIFPA, where we contribute in particular to the Research Network (Iniziativa Specifica) QUANTUM, which pursues a quantum-information approach to strongly correlated matter. Aims of our research within this initiative are to design quantum simulations for lattice gauge theories and analog gravity, to illuminate the role of entanglement in many-body systems, and to design methods to extract complex observables from experimental data.

We are associated partner of the BMWi project EnerQuant: Energiewirtschaftliche Fundamentalmodellierung mit Quantenalgorithmen as well as CRC 1225 ISOQUANT: Isolated quantum systems and universality in extreme conditions.
