The Physics of Information and Quantum Technologies Group promotes research and advanced training aiming at understanding and exploiting the role of quantum physics, of thermodynamics, and of relativity in the encoding, detection, transmission and processing of information, as well as at exploring the insights quantum information brings into fundamental physics.

Namely, our team develops research in Quantum Information, Computation and Simulation, in Relativistic Quantum Information, in Quantum Thermodynamics and Nanoenergetics, and in Quantum Effects in Biology and Open Quantum Dynamics, in the context of a variety of international projects and a doctoral programme.

The Group is part of Instituto de Telecomunicações (IT), a national research institute rated Excellent in its international assessments. It is located in Instituto Superior Técnico (IST, the School of Science and Engineering of the University of Lisbon), in Lisbon, Portugal (see Contact to find out how to reach us).

Welcome to the Quantum Many-Body Dynamics group in Natal!

We are a research group working in the field of ultracold quantum matter at the interface of statistical physics, atomic and molecular physics and condensed matter physics.
