Conventional networking
Fiber, radio and free-space optical transport carry traffic through the network. Scope routing, authentication, segmentation, encryption and operational monitoring.
Quantum networking
Conventional connectivity, post-quantum cryptography and quantum communications have different roles. Build the architecture around the requirement for each layer.
Three distinct layers
A laser link is an optical transport path. The protection of the data and the assurance of the endpoints must be designed alongside it.
Fiber, radio and free-space optical transport carry traffic through the network. Scope routing, authentication, segmentation, encryption and operational monitoring.
Assess cryptographic dependencies and migration to NIST-standardised algorithms, with compatibility, implementation assurance and deployment testing.
Evaluate quantum key distribution and related research in a separate feasibility scope. Specialised hardware, authenticated channels and operating constraints must be tested.

A practical migration path
Each phase is tied to a customer-controlled environment and the agreed scope.
Inventory the cryptographic uses, certificates, keys, devices and dependencies within the assessment boundary.
Consider data sensitivity, retention needs, interoperability and the effort required to change each dependency.
Test selected implementations and interface behaviour in the scoped pilot before an operational migration.
Document ownership, key management, monitoring, recovery and how future cryptographic changes will be introduced.
Optical resilience
Clouds, atmospheric interference and precise pointing are practical optical-link constraints. Site diversity and appropriate alternate paths belong in the service design.
