Google has taken a giant leap forward in the world’s race for quantum supremacy. new computer model – named Sycamore – Today it can perform instantaneous calculations that would take 47 years when done by the world’s most powerful supercomputer (Frontier of Oak Ridge National Laboratory in the USA).

Sycamore has a total of 70 operational qubits, according to an article hosted by AI researchers at Google on the arXiv online scientific paper repository. Similar to the 0 or 1 values ​​of classical computers, qubits allow these two elements to overlap, making calculations run exponentially faster.

Four years ago, Google announced that it had reached “quantum supremacy,” the limit where a quantum computer outperforms all existing machines. This was controversial at the time, but the new article reveals a more powerful device; The 2019 machine outstripped the Frontier by 6.18 seconds, while Syracuse was up 47.2 years.

How has the superiority of Google’s new quantum computer been proven?

To prove their quantum supremacy hypothesis, the article states that the Google team worked with a synthetic benchmark called Random Circuit Sampling (RCS), which allows to identify “different phases driven by the interaction between quantum dynamics and noise.” Quantum noise is a challenge that exists in the operation of such devices. and it deals with the uncertainties and weaknesses of a quantum computer.

For these machines to work, it is essential to deal with this noise to ensure that the states of the qubits are accurately recorded. Steve Brierley, CEO of the quantum company Riverlane, which develops the operating system for quantum computers Deltaflow.OS, told The Telegraph: “The dispute over whether or not we have achieved quantum supremacy is now settled.”

However, the next step is for these quantum devices to begin to perform more practical functions. Also speaking to the British publication, Sebastian Weidt, CEO of the company that launched Universal Quantum, recalls that the success of the show ushered in an era of “utilizing quantum computers.” […] it is really starting to add value to society in a way that classical computers never could.”
