In the proposed architecture of a quantum-secured optical interconnect system, classical data is sent using the SHC method, while quantum key distribution (QKD) adds security. The system uses all-optical transmission, with a clock-embedded local oscillator that synchronizes the data transmission and the QKD terminal, simplifying the architecture for secure data transmission.
