**About the Editors**

**Maria Bondani** (PhD in Physics in 1994) is a Researcher at the Institute for Photonics and Nanotechnologies of the National Research Council. Her scientific activity covers several topics in the field of radiation–matter interaction, with reference to fluorescence studies, nonlinear optics, quantum optics and light detection techniques in different regimes for the generation and characterization of optical states with applications for quantum information. The research activity is mainly experimental but also includes theoretical aspects (development of models, simulations). She is also involved in physics education research and outreach activities, particularly in the fields of quantum physics and quantum technologies.

**Alessia Allevi** (Associate Professor) graduated in 2002 and obtained her PhD in Physics in 2006. Since 2019, she has been an Associate Professor at the University of Insubria in Como (Italy). She is an experimentalist, and her main interests are quantum and nonlinear optics, quantum information and the characterization of different classes of photodetectors. Her research activity is supported by several collaborations with national and international theoretical groups.

**Stefano Olivares** (Associate Professor) received his PhD degree in Physics from the University of Milan, where he is currently Associate Professor at the Department of Physics. He is a theoretician, and his interests include quantum information, quantum estimation, quantum optics, quantum interferometry, and quantum computation. His main contributions are in the fields of quantum estimation of states and operations, the generation and application of entanglement, quantum information, and quantum communication. Although his research activity is mainly theoretical, he is an active collaborator in many experimental groups.
