Quantum Communication research at Deutsche Telekom
Dr. Marc Geitz • T-Labs, Berlin, Germany
Quantum communication is evolving from laboratory demonstrations toward deployable network technologies. This talk provides an overview of quantum communication research at Deutsche Telekom, covering the spectrum from quantum randomness generation and distribution, the realization of quantum-secure networks, quantum sensing, approaches to entanglement distribution, and the use of entanglement as a resource for future communication protocols. These activities are supported by Deutsche Telekom’s dedicated quantum laboratory, a nationwide quantum research network, and strong collaborations with universities, start-ups, and industry partners. Together, these efforts explore practical approaches to quantum networking and contribute toward the long-term vision of a quantum internet.
Dr. Marc Geitz is a physicist and senior Innovation Architect at Telekom Innovation Laboratories (T-Labs) in Berlin, where he leads research and development in quantum technologies. He is currently the lead of the Quantum Lab at T-Labs, an experimental facility dedicated to quantum communication and quantum computing. He has over 20 years of experience in the telecommunications and ICT sectors. Since joining Deutsche Telekom in 2001, he has held several key roles such as Innovation Architect (T-Labs) (focusing on quantum communication, quantum key distribution (QKD), and quantum repeaters), Quantum Lab Lead, Project Field Manager for Cloud IT, a Product Owner at immmr GmbH, and a Lab Manager for Next Generation IT (NGIT).
Education and Academic Research:He holds a doctorate in physics with a background in high-energy physics and particle acceleration, earned from the University of Hamburg (1999).
