It measures just 4cm squared but it possesses almost inconceivable speed. Google has built a computing chip that takes just five minutes to complete tasks that would take 10,000,000,000,000,000,000,000,000 years for some of the world’s fastest conventional computers to complete. That’s 10 septillion years, a number that far exceeds the age of our known universe and has the scientists behind the latest quantum computing breakthrough reaching for a distinctly non-technical term: “mindboggling”. The new chip, called Willow and made in the California beach town of Santa Barbara, is about the dimensions of an After Eight mint, and could supercharge the creation of new drugs by greatly speeding up the experimental phase of development.
