According to a peer-reviewed paper published on March 12 in the journal Science, D-Wave claims to have performed a materials simulation that surpasses the capabilities of even the most advanced classical supercomputers. Specifically, D-Wave said its annealing quantum computer solved a difficult materials simulation problem that would take millions of years on the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory. D-Wave states in its related press release that the achievement is “the world’s first and only demonstration of quantum computational supremacy on a useful problem.” However, some researchers have challenged this assertion, insisting that traditional computing methods may already achieve comparable results. Moreover, some experts take issue with the usage of the term “quantum supremacy,” advocating instead for alternatives like “quantum advantage” or “quantum utility.” Simulation in approximately 20 minutes compared to a million years According to D-Wave’s paper, its annealing quantum computer Advantage2 prototype successfully simulated the properties of complex magnetic materials used in smartphones, medical devices, sensors, and motors. The company reported the simulation was completed in less than 20 minutes. …
