Researchers from quantum computing company D-Wave Systems and Google simulated some materials as much as 3 million times faster than a classical computer could, through the process of quantum annealing.

D-Wave's Andrew King said, "This work is the clearest evidence yet that quantum effects provide a computational advantage in D-Wave processors," which are based on a quantum computing technique that identifies solutions for optimization problems.

The researchers used D-Wave’s 2,000-qubit system to model a programmable quantum magnetic system and simulate exotic magnetism.

They also were able to use a quantum annealing processor to solve a valuable materials science problem.
