- Quantum coherence, coming from quantum superposition, occupies a significant position in the field of physics. We put forward a lower bound of the robustness of multilevel coherence mathematically by optimizing the coherence witnesses via semi-definite programming, which can be direct and easy to evaluate and experimentally accessible. A numerical example is supplemented to illustrate the efficiency of the presented bound.
