# Multidimensional CV-QKD Reconciliation
## Methodology
Transforms physical Gaussian quantum channel into virtual BIAWGN channel, enabling modern error-correcting codes for CV-QKD at low SNR and long distances.
## Key Insights
1. **High-dimensional constructions**: Beyond algebraic dimensions 1, 2, 4, 8 to arbitrary dimensions
2. **Virtual channel construction**: Gaussian → BIAWGN transformation for LDPC code compatibility
3. **HDirac framework**: Open-source simulation for arbitrary dimensions
4. **Trade-off analysis**: Dimension vs reconciliation efficiency vs frame error rate
5. **Reverse reconciliation**: Practical coding schemes for long-distance operation
## Implementation
- Use HDirac (github.com/aff3ct/HDirac) for simulation
- Evaluate LDPC codes at various dimensions
- Optimize for SNR and distance requirements
