Quantum simulations reveal spin transport in 1D materials

Researchers from the Department of Energy's Quantum Science Center (QSC) headquartered at Oak Ridge National Laboratory (ORNL) have achieved a significant milestone by demonstrating the first digital quantum simulations of how spin currents change over time in a 1-D model of a quantum spin material. The results, now published in Physical Review Letters, establish a new, programmable way to use quantum computers to study the transport of spin-a fundamental quantum variable-in materials.
