Researchers document presence of quantum spin liquids, an elusive state of matter never seen before

The Harvard-MIT CUA collaboration led by Lukin, Greiner, and Vuletic reported the first experimental realization of a quantum spin liquid, a highly entangled phase of matter that eluded experimental observation for several decades.  An example of topological state, such as a spin liquid, can help in the search for reliable quantum computers. Predicted about 50...
