Quantum Optical Encryption Enabled by Four-Channel Metasurface Groupoid Structures
Open access0 citations
Abstract
Quantum optical encryption is realized through four-channel metasurface scattering modeled as a groupoid structure. Encryption arises from composite morphisms, and decryption succeeds when the diagram closes. The same architecture extends to reversible unitary quantum operations.
