A Chinese-South African team has successfully established the longest quantum communication link using the Jinan-1 microsatellite. They accomplished image transmission over 12,900 km. The project aims to develop a global quantum network with advanced communication capabilities.
In a significant advancement in the field of quantum communication, a collaborative team from China and South Africa has achieved the establishment of the longest quantum communication link in the world. This accomplishment was made possible through the deployment of an economical microsatellite coupled with portable ground stations, as detailed in a recent publication in the peer-reviewed journal, Nature.
The researchers utilized China’s Jinan-1 quantum microsatellite, which linked Stellenbosch University in South Africa to a base located in Beijing, managed by scientists from the University of Science and Technology of China (USTC). This innovative technology enabled the successful transmission of two distinct images: one depicting China’s Great Wall and the other showcasing the Stellenbosch campus, over an extraordinary distance of approximately 12,900 kilometers.
Furthermore, the research team highlighted in their publication the development of a quantum microsatellite capable of executing space-to-ground quantum key distribution in conjunction with portable ground stations. This represents a substantial progress within quantum communication technology.
Looking ahead, the research team has outlined their ambitious aspirations for future developments. They intend to deploy multiple microsatellites and establish a comprehensive network of optical ground stations, aiming for the creation of a practical quantum constellation. The team envisions this global-scale quantum network as a transformative tool, potentially revolutionizing communication, computing, and sensing capacities across the globe.
In conclusion, the collaborative efforts of the Chinese and South African team in establishing the longest quantum communication link marks a pivotal moment in quantum communication technology. The use of an innovative microsatellite and future plans for a global network indicate the potential for transformative advancements in communication and sensing capabilities. This work is a significant step towards realizing a practical quantum constellation, promising to reshape future technological landscapes.
