  • Images have been securely transmitted by satellite using Quantum Key Distribution (QKD) between ground stations in China and South Africa, a record-breaking distance of 12,900 kilometers (8,000 miles).

The article discusses the establishment of the first world-spanning ultra-secure quantum satellite link between South Africa and China, facilitated by the Micius satellite. This link, which spans over 12,000 kilometers, was achieved through a collaboration involving the University of Science and Technology of China, the University of Vienna, and the National University of Singapore. The quantum communication link uses the principles of quantum entanglement to ensure that any interception attempt would be immediately detectable, providing unprecedented security for data transmission. This development not only marks a significant advancement in quantum communication technology but also has potential implications for global secure communications, potentially revolutionizing how sensitive information is shared across continents. The project underscores the growing capabilities and international cooperation in quantum technology, aiming to create a future global quantum communication network.
