UK’s first Quantum-Safe Long-Distance Communication
British Universities demonstrate first Quantum-Safe Long-Distance Connection over a Quantum Network: Quantum Communication offers unique security advantages compared to classical telecommunications solutions: it is immune to future cyberattacks — even those from Quantum Computers, which, once fully developed, will have the potential to break the strongest cryptographic methods currently in use within a very short […]
New Record for Quantum Key Distribution
Chinese Team transmits Quantum-Encrypted Images over a Distance of 12,900 Kilometers: A group of researchers from China has set a new record in Quantum Communication by using a lightweight microsatellite to transmit a secret encryption code over a distance of around 13,000 km from China to South Africa. Pulses of laser light in specially prepared […]
Successful Kick-off Event
Consortium meets for Kick-off Meeting in Bad Honnef – With around 90 participants, the two-day kick-off meeting of the joint project “Quantenrepeater.Net (QR.N)” began on 13 February 2025 at the Physics Center Bad Honnef. The event opened with a presentation by project coordinator Prof. Dr. Christoph Becher, who introduced the structure and main objectives of […]
Quantum Teleportation over busy Internet Cables
Secure Quantum Applications without special Infrastructure: Researchers at Northwestern University in Illinois have made an important advance for the future of Quantum Communication. In an experiment, they have succeeded in transmitting Quantum Information over a 30-kilometre fiber optic cable that already carried Internet traffic. This opens up the new possibility of combining Quantum Communication with […]
Quantum Teleportation across Saarbrücken
New Paper on Quantum Teleportation published: Researchers from Universität des Saarlandes (UdS) have achieved an important breakthrough in Quantum Communication by demonstrating Quantum Entanglement and Teleportation over a 14 km long fiber link, the “Saarbrücken Quantum Communication Fiber Testbed”. The physicists, led by the professors Dr. Jürgen Eschner and Dr. Christoph Becher, used photon pairs […]
