Abstract An open challenge in the context of quantum information processing and communication is improving the robustness of quantum information to environmental contributions of noise, a severe hindrance in real-world scenarios.Here, we show that quantum skyrmions and their nonlocal topological RCA observables remain resilient to noise even as typ
