D-Wave's claim that its quantum computers can solve problems that would take hundreds of years on classical machines have been undermined by two separate research groups showing that even an ordinary

The company says it has solved the first problem of scientific relevance with a quantum processor faster than could be done with classical computers—but others disagree

D-Wave is about to make waves. The quantum computing firm announced on Wednesday that, for the first time, it was able to “successfully simulate the properties of magnetic materials” using its Advantage2 annealing quantum computer,
