Sky Perfect JSAT is joining an R&D project to demonstrate satellite-based quantum key distribution (QKD) led by Japan’s National Institute of Information and Communications Technology (NICT). 

The project is part of the Space Strategy Fund initiative led by the Japan Aerospace Exploration Agency (JAXA). NICT was selected to lead the project in December with 14.5 billion yen (roughly $99 million) from the fund. 

NICT aims to develop a small, Low-Earth Orbit (LEO) satellite capable of key sharing using quantum cryptographic technologies. SKY Perfect JSAT will contribute to the design and planning of the satellite control system, as well as evaluating candidate satellites for launch. 

Sky Perfect JSAT has experience in R&D for satellite-based QKD and both Sky Perfect JSAT and NICT will explore possibilities for commercializing this technology. 

“In the space industry, the data communications sector — expected to see significant expansion in the coming years— is facing growing demands for higher levels of security. SKY Perfect JSAT remains actively engaged in the development of a satellite-based quantum cryptographic communication network, and will continue to pursue this goal through initiatives such as this R&D project,” Sky Perfect JSAT said in a statement.
