Google Publishes ‘Quantum Supremacy’ Results in Nature Journal

(NYTimes) Google announced on Wednesday in an article in the science journal Nature that it had achieved a long-sought breakthrough called “quantum supremacy,” which could allow new kinds of computers to do calculations at speeds that are inconceivable with today’s technology.
Google said its research lab in Santa Barbara, Calif., had reached a milestone that scientists had been working toward since the 1980s: Its quantum computer performed a task that isn’t possible with traditional computers.
In this case, a mathematical calculation that the largest supercomputers could not complete in under 10,000 years was done in 3 minutes 20 seconds, Google said in its paper.
