HALF SPINS. ‘Haldane, meanwhile, was busy applying the concept of topology to chains of magnetic atoms. These atoms have a quantum property known as spin, and in 1982, he predicted that certain chains of the atoms could show topological properties that result in half spins at either end. Because this quantum property depends on the collective action of the whole chain, rather than on any individual particle, similar phenomena are now being explored as robust ways to encode information in a quantum computer.”
