【Title】Light-matter quantum correlations and the development of quantum technologies in Recife-Brazil

【Speaker】 Daniel Felinto Pires Barbosa, Federal University of Pernambuco, Brazil

【Abstract】The formation of collective entangled states on atomic ensembles is heralded by detection of photons spontaneously emitted by the sample. Its origin is the coherent interaction of atoms with the quantum reservoir of vacuum modes. In the last two decades, many groups have explored this process to devise applications in quantum information. Here I present our recent work on the problem, exploring quantum correlations generated from simple systems, like cold ensembles of two- and three-level atoms. I also review other works of our group with implications for quantum technologies, like in photon pair generation, ultrafast control and NV centers in diamond. Finally, I present the recent projects of our group to develop quantum technologies in Brazil.

【Brief Bio】

Daniel Felinto received his Ph.D. from the Federal University of Pernambuco (UFPE, Brazil). After postdoctoral positions at University of S?o Paulo (Brazil) and Caltech (USA), he joined again UFPE in 2006 as a full professor. His research is focused on applications of optics and atomic physics to quantum information and technology, using techniques for cold atoms, ultrafast control, and quantum optics. He coordinates the Quantum Networks Laboratory at UFPE and is presently coordinating the projects to build a metropolitan quantum network in Recife and to install the Institute for Quantum Technology of UFPE.
