Teleporting quantum information is no longer science fiction. Qunnect, a developer of quantum network technologies, in collaboration with Deutsche Telekom’s R&D unit T-Labs, has successfully performed quantum teleportation over a 30-kilometer distance on a commercial telecommunications infrastructure in Berlin.
In tests conducted in a real-world field environment in January 2026, quantum information transfer was achieved over existing commercial fiber optic cables. The experiment was carried out using Qunnect's commercially available quantum entanglement distribution hardware and Deutsche Telekom's quantum infrastructure in Berlin. This work is of great importance as it represents the first practical test outside a laboratory of the fundamental components required for future “quantum internet” services.
90% Average Success Rate Achieved
During the experiment, quantum bits (qubits) were teleported over a 30 km fiber loop between the T-Labs Quantum Laboratory and a node on Berlin's fiber test network. According to the data obtained, the teleportation accuracy reached an average of 90%, with a peak accuracy of 95% recorded.
One of the most notable aspects was that the operation was performed at a 795 nm wavelength, which is critically important for neutral atom quantum computers, atomic clocks, and high-precision quantum sensors. This paves the way for the future integration of various quantum systems into existing telecom infrastructure.
Performed in Parallel with Data Traffic on Existing Network
Abdu Mudesir, a member of Deutsche Telekom's Board of Management, emphasized that the test conducted in Berlin was performed on a commercial fiber optic network and in parallel with normal data traffic. This development lays the technical foundation for quantum computers to connect across different locations and form a shared processing power. Qunnect CTO Mael Flament stated that teleportation has now evolved from a laboratory experiment into a technology capable of operating in real network cabinets under operator control.
What is Quantum Teleportation?
Quantum teleportation is based on a physical phenomenon called quantum entanglement. Entanglement means that two particles, despite being separated by distance, can instantaneously influence each other's states. Through this method, the quantum state of one particle can be transferred to another particle. However, rather than the physical transfer of a particle, information is transported from one point to another through entanglement.
Quantum teleportation is considered one of the fundamental building blocks of the future quantum internet. This technology will enable applications such as ultra-secure communication with quantum cryptography, distributed quantum computing, secure cloud-based quantum services, quantum data centers, and high-precision sensor networks.
In the next phase, the companies plan to test multi-node teleportation scenarios to increase distance and evaluate broader use cases in metro-scale operator networks.
