Quantum light for quantum technologies | Pascale Senellart (CNRS-C2N, Paris)

Quantum light for quantum technologies | Pascale Senellart (CNRS-C2N Center for Nanoscience and Nanotechnology, Paris) Light, and more precisely quantum light, is a key ingredient of the emerging second quantum revolution. It is the cornerstone of many applications ranging from quantum computing to quantum networks, offering many flavors of “quantumness” and degrees of freedom to encode the information. We will discuss a platform that has recently emerged to generate of single photons: semiconductor quantum dots. With of all the possibilities offered by semiconductor nano-processing and the tools of cavity quantum electrodynamics, these artificial atoms can generate single photons with unprecedented efficiency and near perfect quantum purity. These quantum light sources allow accelerating the development of intermediate scale quantum computing as well as other key functionalities for scalability. We also revisit the fundamentals of light-matter interaction and exploit them to generate new states of quantum light. === The MCQST Colloquium Series features interdisciplinary talks given by visiting international speakers. The monthly colloquium covers topics spanning all MCQST research units and is broadcasted live via Zoom for audiences worldwide. The main goal of the series is to create the framework for idea exchange, to strengthen links with QST leading groups worldwide, as well as to act as an integral part of the local educational environment. === Discover MCQST ▶ Colloquia: https://www.mcqst.de/news-and-events/... ▶ Website: https://www.mcqst.de​​​​​​​ ▶ Twitter:   / mcqst_cluster​   ▶ LinkedIn:   / mcqst​
