An effective strategy for protecting skyrmions in quantum computing devices

A magnetic skyrmion is a versatile topological object that can be used to carry information in future spintronic information processing devices. As potential non-volatile information carriers, excellent endurance and robust retention are desired properties of skyrmions in spintronic devices. However, previous studies have suggested that skyrmions can be easily destroyed at device edges during high-speed operations due to the so-called skyrmion Hall effect.
