There are a number of companies introducing quantum key distribution for secure communications across optical fiber networks but the technology has yet to be applied across a constellation of small satellites in Low Earth Orbit to produce secure global coverage. Until now. On this Constellations Podcast, we welcome Dr. Mark Adams, Associate Professor, Electrical & Computer Engineering, Auburn University to discuss the basics of quantum information processing, how quantum key distribution (QKD) ups the game in data transmission security and moving from the BB84 scheme to fully entangled microwave sources for SmallSats.
