Quantum Time Transfer: using entangled photons for resilient PNT applications

Xairos is developing a global resilient space-based timing architecture using Quantum Time Transfer (QTT), a protocol invented, patented, and perfected by the Xairos team. Accurate timing synchronization is critical for the world’s transportation, networks, financial transactions, data centers, and power grids. Xairos is commercializing QTT to develop the next generation of Position, Navigation, and Timing (PNT), with sub-nanosecond-level accuracy (1000 times better) and the security needed for future networks and applications.
