SECURE NON-TERRESTRIAL NETWORK LINKS UTILIZING QUANTUM KEY DISTRIBUTION INTEGRATED INTO A METASURFACE TRANSCODER NODE WITH HARDWARE POLARIZATION CONTROL

Resumen de: US20260128868A1

0000 The technology described herein enhances the security of non-terrestrial network links by integrating quantum key distribution into an optically transparent metasurface transcoder node with hardware-based polarization control. The metasurface, composed of unit cells of metal-insulator transition material (such as vanadium dioxide, vanadium trioxide, or vanadium pentoxide) leverages the dynamic tunability of the metal-insulator transition material to manipulate the polarization and phase of photons, as needed for quantum key distribution protocols. Hardware level integration ensures secure key distribution with minimal signal loss, enhancing the robustness and security of satellite-terrestrial communication. The system dynamically adjusts to environmental conditions, optimizing performance and ensuring high fidelity in quantum key exchange, thereby providing a robust solution for secure communication in non-terrestrial networks. The transcoder's use of quantum key distribution allows for real-time detection of eavesdropping attempts, as interception of the quantum key exchange alters the photons'quantum states, alerting the system to potential security breaches.
