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. And that supercomputer, the team reports, would consume more energy to run the whole computation than the entire globe uses in a year. However, another group of researchers claims to have already found a way for a classical supercomputer to solve a subset of the same problem in just over two hours.
