The race among quantum computers is full of higher number of qubits and error correction rates. But what problems that need solving now?

A quantum processor solved a problem in 20 minutes that would take a supercomputer millions of years. A supercomputer then did a part of it in about 2 hours.

D-Wave Quantum said Wednesday that it had not only achieved “quantum supremacy,” but had done so using a practical problem, marking an industry first. The quantum-computing company said its Advantage2 system solved a problem in 20 minutes that would take one of the world’s most powerful supercomputers nearly 1 million years to complete.
