...Essentially, Google purports to have pulled off a stunt on a quantum computer that no classical machine—not even the world's most powerful supercomputer—can replicate.
The experiment described in the paper sampled randomly generated numbers produced through a specialized scenario involving quantum phenomena. The researchers said they determined that their quantum computer beat regular computers at the task, which involved calculating the output of certain specialized circuits.
"While our processor takes about 200 seconds to sample one instance of the quantum circuit 1 million times, a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task," the researchers said...
