Quantum Photonics

The Quantum Photonics Group investigates the quantum interaction between light and matter in a solid-state platform.

Our quest is to develop a deterministic photon-emitter interface based using quantum emitters and photonic nanostructures for real-world quantum technology applications within quantum communication towards the Quantum Internet.
