Google Confirms ‘Quantum Supremacy’ Breakthrough

Humans Are Awesome |

Google has now confirmed that it has achieved quantum supremacy with its 54-qubit Sycamore processor. The announcement comes in an article in Nature. The news was unofficially leaked a month ago but now all of the research is public and being scrutinized by the scientific community.

According to Google, Sycamore took 200 seconds to perform a calculation that would take an existing supercomputer around 10,000 years. This is said to indicate that the way the machine made the calculation would not be possible using a non-quantum machine.

The supercomputer that Sycamore has been said to have beaten is operated by IBM which, not surprisingly, has disputed Google's claim. IBM states that its computer could do the task in 2.5 days and not 10,000 years as stated.

Extraordinary Achievement

Although IBM is keen to play down Google’s achievements researchers have welcomed the news. Likely, our ability to produce quantum computers that are suitable and practical for common usage is years down the line but Sycamore does indicate that it is indeed possible.

Scientists have been so enamored with the new machine that they have compared it to the first plane flight undertaken by the Wright Brothers in 1903.
