报告人简介：

Macro Bellini is leader of an experimental research group of the Istituto Nazionale di Ottica (CNR-INO), in a close collaboration with the European Laboratory for Non Linear Spectroscopy (LENS) and the Department of Physics and Astronomy of the University of Firenze. He received his PhD in Physics at the University of Firenze in 1996 and worked then for two years as part of the technical/scientific staff at LENS, Firenze, Italy. From 1999 to 2004, he is a Researcher at the Istituto Nazionale di Ottica (INO), Firenze, Italy. From 2004 to 2010, he is a Senior Researcher at INO-CNR, Firenze, Italy. Now he is a Research Director at INO – CNR, Firenze, Italy. His main scientific interests are quantum optics and laser/matter interactions at very high intensities. In 2017, he was elected as the Optical Society of America (OSA) Fellows for pioneering contributions in ultrafast, highly nonlinear, and quantum optics. In particular, for his seminal experiments on the coherence of supercontinuum and high-order harmonics and for innovative methods of quantum light state engineering.

报告内容简介：

In recent years, quantum state engineering has quickly evolved, with new tools and techniques, such as photon addition and subtraction, which have demonstrated their extreme versatility for performing operations normally unavailable in the realm of Gaussian quantum optics. While photon subtraction can only enhance existing nonclassicality and entanglement, the process of photon addition has the unique capability of creating nonclassicality and entanglement from scratch, whatever the input. After a brief introduction to the techniques developed in our lab along the years, I will focus on the effects of coherent superpositions of single-photon additions, with a special regard to the generation of entanglement between different optical modes. Creating tunable entanglement also between macroscopic systems is a fascinating goal that may help one understand how quantum mechanics blends into classical physics and provide new tools for enhanced communications and sensing.
