This undated handout image obtained October 23, 2019 courtesy of Google shows a Sycamore chip mounted in the printed circuit board during the packaging process. - Scientists claimed on October 23, 2019 to have achieved a near-mythical state of computing in which a new generation of machine vastly outperforms the world's fastest super-computer, known as "quantum supremacy". A team of experts working on Google's Sycamore machine said their quantum system had executed a calculation in 200 seconds that would have taken a classic computer 10,000 years to complete.In a study published in Nature, the international team designed the Sycamore quantum processer, made up of 54 qubits interconnected in a lattice pattern. They used the machine to perform a task related to random-number generation, identifying patterns amid seemingly random spools of figures.The Sycamore, just a few millimetres across, solved the task within 200 seconds, a process that on a regular machine would take 10,000 years -- several hundreds of millions of times faster, in other words.
