Google’s quantum computing achievement
For at least three decades, teams of researchers have been exploring quantum computers for real-world applications in scientific research, engineering and finance. Researchers have dreamed of the day when quantum computers would first achieve “supremacy” over classical computers, in the sense that a quantum computer solving a particular problem faster than any present-day or soon-to-be-produced classical computer system.
In a Nature article dated 23 October 2019, researchers at Google announced that they have achieved exactly this.
Google researchers employed a custom-designed quantum processor, named “Sycamore,” consisting of programmable quantum
