Researchers have succeeded in their aim of not only changing the strength but also the nature of the interaction between microscopic quantum magnets, known as spins. Instead of falling into a state of complete disorder, the especially prepared magnets can maintain their original orientation for a long period. With these findings, the physicists have successfully demonstrated a programmable control of spin interactions in isolated quantum systems.
