Prof. Sara Ducci

Sara Ducci is Professor at Université de Paris at Laboratoire Matériaux et Phénomènes Quantiques (MPQ). After his doctorate (University of Florence, Italy 2000), she occupied a postdoctoral position at Laboratoire Kastler Brossel (2000-2001), followed by a position as temporary assistant professor at Ecole Normale Supérieure de Cachan. She joined the University Paris Diderot( now renamed University of Paris) in 2002, participating to the creation of the Research Unit (MPQ). Her research focuses on the development of semiconductor sources of quantum states of light operating at room temperature and telecom wavelengths; the work ranges from device development to fundamental quantum optics and applications in quantum information. She has been awarded the Louis Ancel Prize of the French Physical Society in 2016 and she is honorary member of the Institut Universitaire de France.

Generation of quantum states of light with AlGaAs chips

Photonic quantum technologies are a promising platform for applications ranging from long-distance secure communications to the simulation of complex phenomena. Among the different material platforms direct bandgap semiconductors offer a wide range of functionalities opening promising perspectives for the implementation of future quantum technologies. In these lectures, I will first introduce the basics of photon pair generation by spontaneous parametric down conversion in nonlinear material as well as the key experiments to characterize the emitted quantum state; then I will review our works on the generation and manipulation of quantum states of light in nonlinear AlGaAs chips.
