The Quantum Information Science and Technology research group is part of the Federal University of ABC (UFABC), Santo André, São Paulo, Brazil. We are a very enthusiastic research group working in São Paulo metropolitan area.


We are interested in most aspects of quantum information science including theoretical and experimental investigations. For a good perspective of our interest please visit our research page. If you are interested in our recent contributions in the field, visit the publication page. Our mission is the exploration of new paths in the great adventure of scientific and technological progress in quantum information.


We are part of the joint initiative “Brazilian National Institute of Science and Technology for Quantum Information (INCT-IQ)”.


The cities in the university name:

A = Santo André; B = São Bernardo do Campo; C = São Caetano


UFABC is a young Brazilian public university. Located in the industrial belt of São Paulo – Brazil’s largest city – in an area known as ABC. Founded in 2006, the UFABC already established a reputation for high-level interdisciplinary research and teaching, being top ranked in several aspects.


Interdisciplinarity – is a key concept at UFABC – has been discussed since the second half of the last century, when a strong need for redeeming the integrity of knowledge led to this approach, which consists of combining efforts from a variety of disciplines to deal with some scientific or technological problem.


Research and innovation are also another pillars of the university. The UFABC is considered, in several ranks, the most international university in Brazil. It is also the Brazilian university with bigger publication impact with roughly a quarter of the publications in the 10% more cited publications worldwide, according to the SIR World Report, from the Scimagoir rank.
