TECHNOLOGY LICENSING OPPORTUNITY: ChronoQuantum Fiber Timing Integrity Monitor

, PTP or fiducial timing systems already in the field. With optional AI-enabled inference fusing temporal, spectral and spatial signatures, the platform converts fragile quantum measurements into actionable operational intelligence, supporting everything from monitor-only awareness to autonomous correction recommendations across two-node links, mesh networks and facility-scale deployments. How it Works A source generates pairs of correlated or entangled photons and distributes one photon from each pair to each endpoint of a fiber link, sharing the same optical infrastructure as the timing network being monitored. Single-photon detectors at every endpoint record exactly when each photon arrives, time-stamped against the local clock, and these arrival records are streamed to a processing layer that looks for coincidences, the moments when photon partners are detected together. The shape, timing and quality of those coincidence patterns form a fingerprint of the link�s health. A physics-based estimator combined with optional machine learning then interprets the fingerprint, reports residual timing error with calibrated uncertainty, classifies the likely cause and recommends whether the system should continue monitoring, alert an operator or feed a correction back to the timing controller. Technical Description The ChronoQuantum Fiber Timing Integrity Monitor sits alongside an existing timing network rather than replacing it, adding a parallel quantum measurement channel that quietly observes the same fiber links the operational system is using. A specialized light source generates pairs of photons that are correlated, meaning the two partners in each pair share a tight, predictable relationship in time, color and sometimes spatial pattern. One partner from each pair travels to one end of the fiber link and the other partner travels to the other end, where ultra-sensitive single-photon detectors record the precise moment each photon arrives. The system uses standard telecommunications wavelengths, roughly the same colors of light already carried by commercial fiber networks, so the diagnostic light can share the same cables and equipment that operators already have in the ground. Advantages � Provides an independent timing observable rooted in quantum physics; not just a re-read of the same synchronization signals � Overlays cleanly on existing White Rabbit, PTP and fiducial timing systems without replacing them � Pinpoints the root cause of drift by distinguishing endpoint electronics from fiber-path, filter or environmental effects � Supports operation over standard telecom fiber and DWDM equipment, making field deployment practical � Scales from two-node links to mesh and facility-scale networks with redundant sources, detectors and failover modes � Offers flexible operating modes from passive monitoring through operator alerts to autonomous correction recommendations Market Applications � High Energy Physics (detector timing, accelerator synchronization, fusion diagnostics) � Quantum Networking and Distributed Quantum Computing (modular quantum interconnects) � Telecommunications (5G/6G backhaul timing, data center synchronization, submarine cable monitoring) � Positioning and Navigation Assurance (GNSS backup via fiber timing, spoofing and manipulation detection) � Sensing (laser ranging, distributed radar and TDOA sensor arrays, scientific instrumentation) TRL 3 U.S. Patent pending LA-UR-26-25338 LANL Tech Partnerships: Unlock the Innovative Potential Los Alamos National Laboratory offers a wide range of cutting-edge technologies and capabilities that may provide your company with a competitive edge in the market and unlock the innovative potential that can enhance, refine, and revolutionize your products.
