The satellite enabled a QKD-secured video call between Beijing and Berlin over a distance of 8,200 kilometers, with a secure key generation rate of 1.3 kbps — a 40% improvement over the original Micius satellite (2016). The demonstration involved researchers from the University of Science and Technology of China (USTC), led by Pan Jianwei, and Germany’s Ludwig-Maximilians-Universität München.\n\nThe mission utilized upgraded entangled photon sources and adaptive optics to reduce atmospheric losses, achieving a quantum bit error rate (QBER) of 2.1%. This marks the first use of low-Earth-orbit (LEO) satellites for routine intercontinental QKD operations, with plans for a constellation of six dedicated quantum satellites by 2030.\n\n- **Source**: [https://www.cas.cn/en/news/highlights/2026/micius2-qkd-20260408/](https://www.cas.cn/en/news/highlights/2026/micius2-qkd-20260408/)\n\n### 2. **EU Launches Quantum Internet Alliance’s Metropolitan Testbed in Paris**\nOn April 6, 2026, the Quantum Internet Alliance (QIA), funded by the European Commission under Horizon Europe, activated a metropolitan-scale quantum network in Paris. The network spans 42 kilometers with six nodes, connecting research institutions including CNRS, Sorbonne University, and CEA Paris-Saclay. It employs twin-field QKD (TF-QKD) protocols to achieve a record secure key rate of 105 kbps over 100 km of deployed fiber —","keywords":["zo-research","dynamic:quantum-cryptography","quantum-computing"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
