Deutsche Telekom and Qunnect Successfully Test Quantum Teleportation Over Live Berlin Network While teleporting people remains science fiction, teleporting quantum information is now a practical reality. T-Labs, the research and development division within Deutsche Telekom, and Qunnect, the quantum networking pioneer, have successfully demonstrated quantum teleportation over a commercial network in Berlin, marking a major milestone in advancing deployable quantum technologies on existing telecommunications infrastructure. By using newly commercial technologies to overcome instabilities and interferences in existing telecom infrastructure, T-Labs and Qunnect demonstrated how a telecommunications operator can integrate quantum teleportation capabilities into operational networks. During trials conducted in a real-world telecom environment in January 2026, the team achieved quantum teleportation over 30 km of [...]

Quantum internet: More than secure networks – a new era of communication In an interview Dr. Matheus Ribeiro Sena from T-Labs’ Quantum Lab explains Marcin Makowski, Senior Communication Specialist at Group Technology, why the quantum internet is more than just a security feature and how current breakthroughs are paving the way for a new era of digital infrastructure. Marcin: Why do we need a Quantum Internet – and what does it mean for customers? Quantum expert Dr. Matheus Ribeiro Sena Matheus: We need the Quantum Internet because it guarantees the security of our digital communications in the long term while opening up completely new service possibilities. Customers will not only benefit from a [...]

Spatial and realistic audio experience from the cloud The technical validation and demonstration of new technologies is one of the main tasks of T-Labs. This is often achieved through the use of demonstrators that bring the innovations to life and clearly illustrate the practical application possibilities and benefits of new technologies. One example is the demonstrator of the new 3GPP voice communication codec "Immersive Voice and Audio Service" (IVAS), which is now available from 5G Release 18. IVAS enables the transmission of spatial audio over mobile networks and is optimized for the highly efficient compression of immersive audio. This enables immersive audio with very low bandwidth, low latency and low computing effort in the [...]
