Deutsche Telekom and Qunnect Test Quantum Teleportation Over Live Berlin Network
Deutsche Telekom's T-Labs and Qunnect have successfully demonstrated quantum teleportation over a live commercial network in Berlin. The trial used commercial hardware and 30 km of fiber optic cable.
Berlin – Deutsche Telekom's research division, T-Labs, and quantum networking pioneer Qunnect have successfully demonstrated quantum teleportation over a live commercial telecommunications network in Berlin. The experiment, conducted in January 2026, utilized Qunnect's commercial quantum hardware integrated into Deutsche Telekom's existing infrastructure.
The trial achieved an average teleportation fidelity of 90% over 30 kilometers of deployed fiber. This demonstration, using commercial-grade components, represents a significant step towards making quantum teleportation services a deployable reality on existing telecom networks.
Quantum teleportation is a fundamental building block for the future quantum internet, enabling the transfer of quantum information between distant locations without physically sending particles. Abdu Mudesir, Deutsche Telekom Board Member for Product and Technology, stated that the experiment proved quantum information can be transmitted over commercial fiber alongside regular data traffic, laying the groundwork for networking quantum computers and future secure communication.
According to Qunnect, the demonstration shows that the building blocks of teleportation can operate within a real network environment under operator control, moving it from a lab experiment to a deployable technology. Applications enabled by quantum teleportation include quantum cryptography, distributed quantum computing, and networks of quantum sensors.
The successful trial follows a series of prior field tests by the partners. Future plans include extending the demonstration to multi-node configurations and increasing the distance for quantum state transfer to evaluate broader deployment scenarios.
