IBM announces new quantum computing results

IBM (IBM) announced new results that its quantum computer can simulate real magnetic materials with results that match neutron scattering experiments. The work, reported in a pre-print, was conducted by scientists from the U.S. Department of Energy-funded Quantum Science Center at Oak Ridge National Laboratory, Purdue University, University of Illinois Urbana-Champaign, Los Alamos National Laboratory, the University of Tennessee and IBM. The company said, “The ability to design new materials-such as better superconductors, more efficient batteries, or novel drugs-depends on understanding quantum behavior that is often challenging for classical methods to model. While quantum computers are expected to address this challenge, it has remained unclear whether today’s processors could deliver quantitatively reliable simulations of real materials. These results show that current quantum hardware, combined with new algorithms and quantum-centric supercomputing workflows, can already simulate properties of materials, which in general, can be difficult to predict using classical methods alone.”
