• Quantum data teleported 19 miles across German capital with 95% peak accuracy The trial recorded teleportation fidelities at an average of 90 percent. • Researchers in Berlin have teleported quantum data across a 19-mile loop of commercial fiber in one of the most advanced quantum networking tests on regular telecommunications infrastructure. • The achievement, made in January 2026, was carried out by T-Labs, Deutsche Telekom’s research and development division, in collaboration with Qunnect, a quantum networking company based in Brooklyn, New York. • Deutsche Telekom stated that the teleportation ran alongside regular data traffic on the same metro fiber cables, showcasing that future quantum services could coexist with today’s city networks. • The experiment used Qunnect’s commercial entanglement distribution hardware and Deutsche Telekom’s quantum infrastructure in Berlin. • “Our fiber optic network is quantum ready,” Abdu Mudesir, Telekom’s executive board member for product and technology, pointed out.
Article Summaries:
- In January 2026, Deutsche Telekom’s T‑Labs, together with U.S. quantum‑networking firm Qunnect, successfully teleported quantum data over a 19‑mile (30‑km) loop of commercial fiber in Berlin. The experiment achieved a peak teleportation fidelity of 95 % and an average of 90 %, demonstrating that quantum information can be transmitted with high accuracy while co‑existing with regular data traffic on the same metro cables. Using Qunnect’s Carina entanglement‑distribution platform and Deutsche Telekom’s quantum infrastructure, the trial showed that quantum teleportation can operate in standard network racks under real‑world conditions, paving the way for future quantum‑ready telecom services.
