Google may have taken the first step toward "superiority" in quantum computers



Google says that Sycamore, its 53cc quantum computer, was able to calculate evidence in three minutes and 20 seconds, indicating that the numbers generated by a random number generator are actually random. It would theoretically take Sumit, the most powerful supercomputer in the world, for about 10,000 years, to fulfill the same problem ̵

However, Google's claim has already raised controversy. In an interview with FT Dario Gill, head of research at IBM, said the company's claim was "indeterminate – it's just wrong". He said Sycamore does not pass the litmus test for general-purpose quantum computers, as it is designed to solve a specific problem. Part of the issue here is the term "quantum domination" itself. Created in 2012 by theoretical physicist John Preskil, it must mean the moment when a quantum computer is created that can perform calculations that are impossible for even the most powerful supercomputers. In an area as hotly contested as quantum calculations, the first research team to claim quantum dominance is big work. According to an anonymous source FT with whom he spoke, the team who wrote the paper did not want to use the term for fear that they would come off as arrogant.

However, other computer scientists have been less critical of the breakthrough. Daniel Lidar, a professor of engineering at the University of Southern California, told FT that the company was "demonstrating a path to a scalable quantum computer." Whether you determine what Google has managed to do with Sycamore as a quantum computer or not is in some ways irrelevant. The important thing here is that the company was able to solve some complex problems on the way to creating a complete quantum computer. We may still be years and years away from quantum calculations that change our daily lives, but Google's achievement is an important first step.
