Article Summaries:
- Deutsche Telekom’s T‑Labs has demonstrated quantum teleportation over 30 km of live, commercial fiber in Berlin, using Qunnect’s commercially available Carina platform. The test, which achieved an average fidelity of about 90 %, showed that quantum information can be transferred via entanglement rather than by physically moving qubits. Cisco has replicated the same hardware and procedure to link data centres in New York, indicating the approach works across different networks. The demos used 795 nm photons, a wavelength compatible with neutral‑atom quantum computers and sensors. The milestone moves quantum communication from laboratory experiments toward deployable telecom infrastructure, with future work aimed at longer distances and multi‑node networks.
