"quantum simulators simulate/ solve specific problems' complex models (quantum computers aren't yet universally useful)... spin centers: atom-sized quantum magnetic object chains placed in crystal, storing quantum information, communicating with other spin centers, simulating variety of magnetic phases of matter/ transitions between these phases, laser controlled... possible to place spin centers in up to 3D, enabling study of more efficient information storage/ transfer... room temperature quantum computers"
