Scientists electrically detect quantum spin liquid in ruthenium trichloride

Researchers have successfully extracted spin information from an insulator electrically. This breakthrough could enable robust topological quantum computers. A device made of ruthenium trichloride and platinum allowed scientists to detect spin states within the insulator by measuring changes in electrical resistance. This overcomes a major hurdle for applying quantum spin liquids. This achievement paves the way for controlling and integrating these exotic magnetic states into future electronic and quantum technologies.
