This project explores quantum-classical hybrid networks, with emphasis on routing logic, entanglement distribution, and midpoint heralding using NV-centre-based repeaters. 

The team designed a software-defined central planner that dynamically selects optimal paths based on quantum decoherence parameters such as bounces and depolarising error rates.

A sequence diagram illustrating quantum entanglement swapping between a source and destination via multiple repeaters. It shows the flow of messages and swap results coordinated by a Central Planner that manages network state, weight calculations, and entanglement sequences.
