Abstract:
A silicon nitride photonic integrated QKD receiver employing tunable couplers is demonstrated, enabling on-chip reconfigurability. The proposed approach achieves low quantum bit error rates below 1.5% across different receiver configurations, providing a migration strategy towards multi-protocol quantum-secured communication with optimized on-chip tuning.
