Qampus - Research and Development (R&D) Teams

OPTI-Q4: Research and Industrial Applications in Photonic Quantum Technologies

Trainer: Frédéric Grillot

The aim of this course is to introduce R&D teams to the fundamentals and applications of quantum photonics. The program will cover core principles, technological building blocks, quantum communications, sensors/imaging, and provide an overview of key players and the value chain. A strategic workshop will transform these concepts into use cases and roadmaps, while the final day will facilitate networking and collaboration.
