A group of researchers at US tech giant Google are working on a quantum computer, which they hope to show as soon as next year, can calculate in one second the same amount of data it takes a supercomputer to process in one day.

“The chip has been made and we have been testing it and we’re seeing if we can get this to work,” said John Martinis, a pioneer in quantum technology research, who in 2014 joined Google with his team to head up its quantum-hardware effort. The aim of this research at Google is to build the first useful quantum computer.
