Field Demonstration of a Fully Managed, L1 Encrypted 3-Node Network with Hybrid Relayed-QKD and Centralized Symmetric Classical Key Management

We successfully demonstrated a fully-managed, field-deployed, three-node QKD ring network with L1-OTNsec encryption. The network employs a hybrid scheme of QKD and classical yet quantum-safe centrally-generated symmetric keys to support point-to-point and relay consumers.
