Reasons to pursue:
Current space communication systems are fiber-based and only offer short-range communications. While there are optical/laser communication alternatives they are constrained by limited sightlines. Also, with the rise of critical and valuable data transmissions, there is a need for secure, and safe communication systems which will be enabled by QKD (quantum key distribution) in these quantum communication networks. Through this mission, we will be able to validate long-range communication networks that are also secure and efficient for future applications.
Cubesats offer the possibility of validating such a technology with quicker, more efficient turnaround times
