China’s top quantum research group said its Jiuzhang quantum computer produced results in minutes that would take 2+ billion years by the world’s No. 3 powerful supercomputer. That exceeds Google’s prototype quantum computer which, last year, came up with a result in minutes that it estimated would take a supercomputer 10,000 years. The two quantum computers work differently: China’s University of Science and Technology’s computer manipulates photons, whereas Google’s builds quantum circuits via super-cold superconducting metal.

The world’s fastest supercomputers are ranked twice a year, and Innovative Computing Laboratory director Jack Dongarra, one academic behind the rankings, noted that the Top500 list of the world’s fastest high-performance computing (HPC) systems is showing “flattening performance” due to the slowdown of Moore’s Law. In the most recent ranking, Japan’s Fugaku ARM-based supercomputer set a record of 442 petaflops. In 2021, however, the first exascale — 1,000 petaflops — supercomputers are expected to appear, including one from the Oak Ridge National Laboratory in Tennessee.
