Colourful Skyrmion Useful for Quantum Communication

Researchers have, for the first time, generated broadband colored skyrmions using on-chip ferroelectric spherulites, addressing a key limitation in the potential of these topological spin textures for advanced information technologies. Skyrmion configurations have previously been observed across diverse physical systems including liquid crystals, ferroelectric or magnetic domains, quantum Hall systems, and Bose-Einstein condensates, suggesting broad applicability beyond simple magnetic storage. However, existing skyrmions typically hindered efficient information transfer; this new approach overcomes that challenge by creating skyrmions capable of operating across the entire visible spectrum. The team’s work, detailed in eLight, extends skyrmion-based technologies to broadband applications like optical communication and high-capacity data storage, where wideband capability is essential. The potential of skyrmions, localized, topologically protected…
