Summary

Tobias Heindel leads a group called Quantum Communication Systems at the TU Berlin. They generate single particles of light called photons and use them to encode quantum information and transfer it between parties. This method of communication is ultra secure and provably secure based on the laws of quantum physics. The research group works with semiconductor quantum dots and other quantum emitters to create quantum light sources. While the development of a quantum internet is a long-term mission, quantum communication systems are already available and can be used for quantum-secured communication. Tobias Heindel shares his career journey from studying physics to becoming a group leader at TU Berlin. He discusses his research projects, including generating single photon states and entangled photon states from solid-state atoms for quantum communication. He also highlights the importance of collaboration and exchange with researchers around the world. Tobias expresses his wishes for a permanent position, the ability to offer permanent positions to his team members, and the establishment of an institute for solid-state quantum networking. During his takeover of the Real Scientists Nano Twitter account, he plans to introduce his team, showcase their lab work, and discuss the quantum ecosystem in Berlin.
