Quantum Communication Systems Group

Welcome to the websites of Heindel group! Our Quantum Communication Systems group is a BMBF-funded Junior Research Group associated with the Institute of Solid State Physics at the Technische Universität Berlin. Under the leadership of Dr. Tobias Heindel we are researching in the field of photonic quantum technologies, building blocks for the quantum internet and secure communication systems of the future - protected by laws of quantum physics! 

For this purpose, we develop so-called quantum light sources together with our cooperation partners, which can generate single or entangled photons at different wavelengths. We research their properties for applications which we test in our laboratory but also in field applications. The quantum technologies we develop focus on quantum emitters embedded in solid state structures (e.g. epitaxial semiconductor quantum dots, 2D materials, etc.). We use the generated non-classical light field states to implement quantum cryptographic protocols that can subsequently be scaled to quantum networks. Have fun exploring our website!
