A collaborative team from China and South Africa has successfully established the longest quantum communication link using the Jinan-1 microsatellite and portable ground stations. This achievement allows for the transmission of images over a distance of 12,900 kilometers and sets the stage for future global quantum networks with advanced communication capabilities.
A collaborative achievement by researchers from China and South Africa has led to the establishment of the world’s longest quantum communication link, as reported in a recent article published in Nature. This accomplishment leverages the capabilities of an economical microsatellite alongside portable ground stations to facilitate advanced communication methods.
Utilizing the Jinan-1 quantum microsatellite, the team achieved a remarkable feat by connecting Stellenbosch University in South Africa to a base in Beijing operated by researchers from the University of Science and Technology of China (USTC). This process enabled the successful transmission of two distinct images over a distance of 12,900 kilometers, including one of the Great Wall of China and another of the Stellenbosch campus.
The development of a quantum microsatellite, enabling space-to-ground quantum key distribution, represents a significant advancement in quantum communication technology. This innovative approach underscores the potential for more secure and efficient transmission methods across vast distances in the future.
The research team is looking toward the future with grand ambitions, aiming to deploy multiple microsatellites and establish an extensive network of optical ground stations. Their vision includes creating a practical global quantum network that could transform communication, computing, and sensing capabilities on an unprecedented scale.
In conclusion, the establishment of the longest quantum communication link by the China-South Africa collaborative team marks a significant milestone in quantum communication technology. The use of the Jinan-1 quantum microsatellite and future plans for a global quantum network suggest transformative potential for various fields, highlighting the importance of continued research and innovation in this domain.
