A joint team from China and South Africa established the longest quantum communication link using the Jinan-1 quantum microsatellite, enabling long-distance image transmission. Their future plans include developing a broader quantum network to enhance communication capabilities and technological advancements.
A collaborative effort between scientists from China and South Africa has led to the establishment of the world’s longest quantum communication link, marking a significant advancement in the field. Utilizing an affordable microsatellite and portable ground stations, this remarkable achievement was shared in a recent article published in Nature, an esteemed peer-reviewed scientific journal.
The innovation utilizes China’s Jinan-1 quantum microsatellite to connect Stellenbosch University in South Africa with a research base in Beijing, overseen by scholars from the University of Science and Technology of China (USTC). This connection enables long-distance quantum communication, facilitating the transmission of images.
Achieving a remarkable distance of 12,900 kilometers, two images were successfully transmitted using the quantum microsatellite—one depicting China’s iconic Great Wall and the other showcasing Stellenbosch University’s campus. The research team has created a quantum microsatellite capable of conducting space-to-ground quantum key distribution, representing a significant advancement in quantum technology.
Looking ahead, the research team has outlined ambitious plans for expanding their work by launching multiple microsatellites and establishing an extensive network of optical ground stations. Such developments aim to create a broader global quantum network that would enhance communication, computing, and sensing capabilities significantly and could shape the future of quantum technology.
In summary, the collaboration between Chinese and South African researchers has culminated in establishing the longest quantum communication link, featuring a microsatellite that enables long-distance image transmission. With aspirations for a global network of optical ground stations and microsatellites, this breakthrough represents a pivotal step toward advancing quantum communication technology and its practical applications in various fields.
