Google may have just ushered in an era of ‘quantum supremacy’

  Google may have just ushered in an era of ‘quantum supremacy’ ‘The first computation that can only be performed on a quantum processor’Google’s quantum computer was reportedly able to solve a calculation — proving the randomness of numbers produced by a random number generator — in 3 minutes and 20 seconds that would take the world’s fastest traditional supercomputer, Summit, around 10,000 years. This effectively means that the calculation cannot be performed by a traditional computer, making Google the first to demonstrate quantum supremacy.

Google has officially announced that it’s achieved quantum supremacy in a new article published in the scientific journal Nature. The announcement comes exactly one month after it initially leaked, when Google’s paper was accidentally published early. Now, however, it’s official, meaning the full details of the research are public, and the broader scientific community can fully scrutinize what Google says it’s achieved.

Google says that its 54-qubit Sycamore processor was able to perform a calculation in 200 seconds that would have taken the world’s most powerful supercomputer 10,000 years. That would mean the calculation, which involved generated random numbers, is essentially impossible on a traditional, non-quantum computer.

Google may have taken first step towards quantum computing 'supremacy'

  Google may have taken first step towards quantum computing 'supremacy' Google may have made a breakthrough on the path toward creating a viable quantum computer. In a research paper briefly published to NASA's website and only seen by the Financial Times, the company reportedly claims to have achieved a feat known as "quantum supremacy." That is, the search giant says it has successfully created a computer that's able to complete a calculation that is virtually impossible for traditional computers to perform. Google says Sycamore, its 53-qubit quantum computer, was able to calculate a proof in three minutes and 20 seconds that shows the numbers created by a random number generator are in fact random.

In a new scientific paper, Google researchers claim for the first time to have demonstrated " quantum supremacy ," where a quantum computer outperforms a traditional one.

Google 's quantum breakthrough means quantum 's finally getting serious. In a leaked paper, Google revealed it had built a Some researchers, including Benjamin, reckon that the term quantum supremacy , which was popularised by the theoretical physicist John Preskill, is a little overblown.

Unsurprisingly, IBM, the company that operates the supercomputer that Google claims to have beaten, and a key quantum computer competitor, is disputing Google’s claims. In a blog post published pre-emptively on Monday, the company said that the same task could be performed on a classical system in just 2.5 days, rather than the 10,000 years that Google is claiming. IBM says that Google “failed to fully account for plentiful disk storage” when estimating how long its traditional supercomputer would take to perform the calculation.

Despite IBM’s attempts to downplay Google’s achievement, many in the research community welcomed the news, with scientists quoted by The New York Times likening Google’s breakthrough to the Wright brothers’ first plane flight in 1903. We may still be years away from having quantum computers that are useful for practical tasks, but Google’s findings could finally have provided proof that such a future is possible in the first place.

Google Confirms It Has Achieved Quantum Supremacy. Now What? .
IBM has already refuted its competitor's claim.Google announced today that it has finally pulled off the computing benchmark, after a leak last month hinted at the feat. The company claims its quantum computer runs on a 54-qubit chip called Sycamore and took only 3 minutes and 20 seconds to calculate a problem that would take the world’s fastest computer 10,000 years to solve, Google says.
