Mil-Grade Free Space QKD Tracking System
A weapon-grade, customized motorized telescope tracking system engineered for relentless day and night operations up to an astonishing 10km. Built to the most extreme military specifications, it delivers completely unstoppable, zero-compromise defense superiority.
Explore Tactical Dominance →Built for the work between research and deployment
Match the optical source, encoding method and control layer to the experiment — from ready-to-deploy EPS modules to high-brightness PPKTP sources and pulsed weak coherent sources.
Bring timing, counting and data handling into the same architecture with FPGA-based post-processing, eight-channel coincidence counting and PTP synchronisation.
Select a QKD architecture for the link you need to build. Arquis supports free-space and fibre demonstrations across BB84, MDI-QKD, decoy-state and continuous-variable approaches.
Build the system
your programme needs.
Start with a subsystem, a deployable photon source or a QRNG. Scale into a laboratory, protocol demonstrator or a synchronised quantum network as the programme matures.
Arquis combines hardware, FPGA post-processing, protocol implementation and educational platforms so engineering teams can focus on the experiment and the application.
