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

1. Thermal Source QKD: Single thermal source drives passive QKD access network architecture
2. Capacity Scaling: Achieve OTP encryption rates comparable to 10-Gbps classical access networks
3. Passive Network Design: Eliminate active components for simplified, scalable quantum access
4. 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
