D-Wave Quantum said that its Advantage2 annealing quantum computer achieved quantum supremacy on a practical, real-world problem. A new peer-reviewed paper published in Science, "Beyond-Classical Computation in Quantum Simulation," said D-Wave's system has outperformed classical supercomputers in simulating quantum dynamics in programmable spin glasses, complex magnetic material simulations with significant business and scientific applications. In this context, quantum supremacy refers to a quantum computer performing a computational task that is not feasible for even the most powerful classical supercomputers within a practical timeframe. D-Wave said the magnetic materials simulation problem would take nearly 1 million years and more energy than the world's annual electricity consumption if attempted on a classical GPU-based supercomputer, which D-Wave said Advantage2 achieved it in minutes.
