A Shared Aperture for Quantum and Classical Skies: Modeling Dual-Band Reconfigurable Surfaces

As the telegraph and telephone once learned to share a single post, so this design envisions one polished pane carrying both quantum keys and everyday signals—a scheme still on the drawing board, not yet proven in brass and glass.
LONDON, 20 AUGUST —
A theoretical model proposes a dual-band reconfigurable intelligent surface (RIS) capable of supporting both quantum key distribution at 850 nm and classical S-band communication in satellite-to-ground links, with simulations suggesting reduced quantum bit error rates and improved signal quality; full hardware implementation remains experimentally unverified.
