New Study on Quantum Teleportation published
Article reports on new Breakthrough in Teleportation: Researchers at the University of Illinois at Urbana-Champaign have recently demonstrated the transmission of Quantum Information using single photons. They achieved a 94% fidelity. This was made possible by the use of a nanophotonic platform that has the potential to significantly enhance the efficiency of Quantum Communication. Although […]
Progress in Quantum Networks
RPI lays the Foundation for Future Connected Quantum Systems: The development of reliable and scalable Quantum Networks is one of the greatest challenges in modern physics. A key prerequisite for this is the use of entangled Quantum Particles: they enable the fast and tap-proof transmission of Quantum Information over long distances. However, the entanglement disappears […]
India’s first quantum secured Network
STL Tech and C‑DOT demonstrate India’s first quantum secured Network with Multi-Core Fiber: STL Tech, a global pioneer in optical and digital technologies, has successfully demonstrated, in collaboration with the Centre for Development of Telematics (C‑DOT), India’s leading telecommunications research and development center, India’s first Quantum Key Distribution (QKD) transmission over a 100 km long […]
Overview Article on Quantum Communication published
New Article on long distance Quantum Communication: Quantum Communication complements traditional communication methods and is considered a key technology to ensure the security of information transmission even in the age of powerful Quantum Computers. Through Quantum Key Distribution (QKD), for example, tap-proof communication keys can be generated. At the same time, the technology opens up […]
Quantum Key Distribution realized over Long Distances
Breakthrough in Tap-Proof Communication – Europe moves forward with Quantum Encryption: Thanks to its immunity to cyberattacks, Quantum Communication offers unique security advantages compared to traditional telecommunications solutions and is considered a key technology for secure data transmission in the future. Recently, a team of researchers succeeded in implementing Quantum Key Distribution (QKD) under real-world […]
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 […]
