A quantum computing milestone is immediately challenged by a supercomputer

There’s no clear quantum advantage yet in tests of real-world problems

The tug-of-war between quantum computers and classical computers is intensifying.

In just minutes, a special quantum processor, called a quantum annealing processor, solved a complex real-world problem that a classical supercomputer would take millions of years to complete, researchers claim March 12 in Science.
