Quantum Access Network with Thermal Source QKD
Core Concept
Quantum Key Distribution (QKD) provides physically-secure keys via one-time-pad encryption. Current PON-based QKD access networks fall short of classical 10-Gbps capacity demands. A passive thermal-source-driven architecture achieves record capacity with single thermal source powering the network.
Key Methodology
- Thermal Source QKD: Single thermal source drives passive QKD access network architecture
- Capacity Scaling: Achieve OTP encryption rates comparable to 10-Gbps classical access networks
- Passive Network Design: Eliminate active components for simplified, scalable quantum access
- Multi-User Support: Scale to hundreds of users with passive quantum network architecture
Implementation Patterns
- Design passive QKD access networks using thermal sources
- Scale quantum key distribution to PON-based multi-user architectures
- Optimize OTP encryption rates for practical deployment
- Integrate QKD with existing classical access network infrastructure
Applications
- Ultra-large-capacity QKD access networks
- Multi-user quantum key distribution systems
- Passive quantum communication infrastructure
- Quantum-secure broadband access networks
