Quantum keys can fail quietly. Loss and noise can leave you with bits, but no secrecy. We model the cliff to expose silent breakage before it becomes a system risk.

Quantum dense coding protocols using different entangled states are comparatively analyzed under ideal and Pauli noisy environments. Theoretical and Qiskit simulation results show excellent agreement, revealing trade-offs in robustness, circuit depth, and gate complexity, providing a practical framework for future quantum communication networks.
