Barreto Group

Research interests and activities

My group’s efforts cover a broad spectrum of topics. Our ultimate goal is to develop techniques, devices and solutions that enable exploiting the potential of integrated photonics with special emphasis on quantum information processing. We explore light-matter interaction for the efficient generation of quantum states of light, devise schemes for scalable photonic circuits and analyse the trade-offs in complex photonic systems.
