Our group works on quantum information science and quantum optics, in particular, on the theory of quantum entanglement and various issues on quantum metrology. Our work is strongly connected to the European Research Council (ERC) Starting Grant GEDENTQOPT, the CHIST-ERA grant Quasar and the QuantERA grant CEBBEC, which fund large part of our activities. We are at the University of the Basque Country in Bilbao, Spain.
