Research Focus: Photonic Quantum Networks

Our research mission is to advance photonic quantum technologies that will form the foundations of a future quantum internet. We develop quantum light sources, spin–photon interfaces, and other essential components using a wide range of quantum emitters, including semiconductor quantum dots, defects in solid-state crystals, emerging 2D materials, and molecules. With these building blocks, we design and demonstrate protocols for quantum communication and information processing—both in controlled laboratory environments and in real-world field experiments. Ultimately, our vision is to scale these technologies into large quantum networks that could one day span the globe and enable entirely new capabilities in communication and computing.

In summary, our activities focus on three core areas of quantum technologies:

• Foundations: Generation and control of photonic- and spin-qubits
• Building blocks: Quantum light sources, spin–photon interfaces, and related components
• Protocol implementations: For real-world quantum communication and networking
