China claims fastest quantum computer in the world

A team of Chinese scientists have developed the most powerful quantum computer in the world, capable of performing at least one task 100 trillion times faster than the world’s fastest supercomputers.

In 2019, Google said it had built the first machine to achieve “quantum supremacy,” the first to outperform the world’s best supercomputers at quantum calculation, Live Science previously reported. (IBM disputed Google’s claim at the time.) The Chinese team, based primarily at the University of Science and Technology of China in Hefei, reported their quantum computer, named Jiuzhang, is 10 billion times faster than Google’s. A description of Jiuzhang and its feat of calculation was published Dec. 3 in the journal Science. Assuming both claims hold up, Jiuzhang would be the second quantum computer to achieve quantum supremacy anywhere in the world.
