Light reveals unique quantum spin liquid state, promising error-free computing

A team of researchers affiliated with UNIST has succeeded in identifying traces of the Kitaev quantum spin liquid (QSL) using light. The Kitaev QSL represents a special quantum state that could pave the way for the development of error-free, large-scale quantum computers. However, experimentally confirmed instances of this phenomenon within materials have been scarce, prompting ongoing efforts to discover suitable candidate materials.
