Materials science simulations conducted by a multi-institutional research team on a quantum computer generated accurate results that can be confirmed with neutron scattering experiments and other practical methods.

Investigators at the U.S. Department of Energy's Oak Ridge National Laboratory, the University of Tennessee, Knoxville, Purdue University, and D-Wave Systems embedded an existing quantum annealing model within a quantum computer. The results indicated that quantum resources can analyze magnetic materials' structure and properties, which could deepen understanding of novel phases of matter conducive to data storage and spintronics.

"We completed the largest simulation possible for this model on the largest quantum computer available at the time, and the results demonstrated the significant promise of using these techniques for materials science studies going forward," said UT Knoxville student Paul Kairys.
