PNT, Quantum Time Transfer and Entangled Photon Systems

On the Constellations podcast, the critical role of timing in both commercial and military applications is explored. Hear from David Mitlyng, CEO of Xairos as he discusses quantum communications as a next-gen timing solution. He explains how quantum hardware is more mature and practical than quantum computing and highlights quantum time transfer – the secure, precise delivery of time using entangled photons. David shares how this technology can be rapidly deployed at scale, integrated into satellites and ground systems. He also covers efforts around grandmaster clocks, the role of AI and the challenge of moving beyond GPS, which remains deeply embedded in today’s infrastructure.
