Abstract An open challenge in the context of quantum information processing and communication is improving the robustness of quantum information to environmental contributions brynje tactical beanie of noise, a severe hindrance in real-world scenarios.Here, we show that quantum skyrmions and their nonlocal topological observables remain resilient to noise even as typical entanglement witnesses and measures of the state decay.This allows us to introduce the notion of digitization of quantum information based on our discrete topological quantum observables, foregoing the need for robustness of entanglement.We compliment our experiments with a full theoretical treatment that unlocks the quantum mechanisms behind the topological behavior, explaining why the topology leads to robustness.Our approach holds coleman 125 ut parts exciting promise for intrinsic quantum information resilience through topology, highly applicable to real-world systems such as global quantum networks and noisy quantum computers.
