Abstract
We demonstrate chip-to-chip entanglement-based quantum key distribution using fully integrated silicon photonic transmitter and receiver circuits with path encoding, achieving secure key generation over an 80 km two-core fiber spool, advancing scalable integrated quantum communication networks.
