In this episode of Constellations, we first get a primer about quantum physics and quantum technology, then a discussion about the growing field of quantum communications, and how it applies to the space industry. There are only a handful of companies specializing in this technology, including SQT, a company that claims to transform the world’s networks for the quantum revolution. SQT CEO David Mitlyng joins us to explain the ins and outs of Quantum Key Distribution (QKD), applications in Position, Navigation, and Timing (PNT), and quantum communications’ defense implications.
