SQIG is a research group of Instituto de Telecomunicações established on May 31, 2006, recognised as an associated research unit of the Department of Mathematics of IST, focused on logic and computation with emphasis on the fields of information security and quantum computation and information.

Our group is carrying out research at the interface of Quantum Information Theory and Quantum Many-Body Physics, particularly Quantum Chemistry. We resort to analytic approaches complemented and guided by computational studies to gain universal insights into interacting quantum many-body systems. A particular emphasis lies on the concept of reduced density matrices and the ground state problem.
