(CNBC) Hundreds of start-ups have flocked to the space sector, bringing sophisticated technologies that include quantum computing, as well as AI, phased array radar, space-based solar power, “tiny” satellites and services.space-based solar power, “tiny” satellites and services.
The growing flow of data from satellites has raised concerns about data security. SpeQtral, based in Singapore, plans to build encryption keys based on the laws of quantum physics to protect space-to-Earth communications. “The security of any communications is essential,” says Chune Yang Lum, CEO of SpeQtral, which has raised a $1.9 million seed round led by Space Capital, the venture arm of Space Angels. Quantum encryption has been touted as practically unbreakable.
This is a lengthy article with discussion of the technologies and agencies involved in the space sector. Only the quantum discussion was referenced here the larger context also of interest and worth a read to understand the ecosystem.
