Space-based Quantum Key Distribution

~60 min · 15 stations

Space-based Quantum Key Distribution is a self-paced learning path in Astronomy & Space Exploration, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify fundamental principles of quantum mechanics; explain why current encryption methods face threats; describe why satellites improve quantum signal range.

Conductor

The Conductor

All aboard the quantum express. We are mapping the future of secure space communications from orbit to your local ground station.
