Google claims that “quantum supremacy’ and some others say to keep them on a qubit

BERLIN (Reuters) – Google (GOOGL.(O) said on Wednesday it had achieved a breakthrough in the computer-research, and, in the course of solving a complex problem in just a few minutes by using a so-called quantum computer, which would be the most powerful super computer thousands of years to crack it.

The official confirmation of a breakthrough in quantum computing came in a paper published in the science journal Nature, after weeks of controversy following the leak of a draft on the question of whether Google’s claim of “quantum supremacy” in effect.

Computer scientists have for decades sought to harness the behavior of sub-atomic particles that can exist simultaneously in different member states, as opposed to the “real” world, and the people around them.

Thus, while traditional computing is based on bits, zeroes and ones, quantum computing uses quantum bits, or qubits, which can be both one and zero at the same time.

This property, called superposition, is exponentially multiplied if the qubits are connected to each other. The more qubits that are to be aggregated, the more powerful a quantum computer is.

But there’s a catch: the Quantum researchers will need to cool the qubits to be close to absolute zero to reduce vibrations, or “noise,” which causes an error to creep in to their calculations. It is a very challenging task, which Google research team has made significant progress.

CEO, Sundar Pichai, in comparison with the performance of the construction of the first rocket to leave the Earth’s atmosphere, and hit the edge of the area, an advance that led to the interplanetary travel to the realm of the possible.

“For those of us who have been working in the fields of science and technology, it is the “hello world” moment we’ve been waiting for – to be the most meaningful milestone to date in the quest-to-date, to make quantum computing a reality,” Pichai wrote in a blog post here


Google has developed a micro-processor, which is called the Property, that’s a total of 54 qubits. Measuring approximately 10 mm, it is made with aluminum and indium, share, sandwiched in between two silicon wafers.

In their experiment, the researchers were able to find 53 of the qubits connected to each other in a grid pattern to interact with it in a so-called quantum state.

Then, the quantum computer is a complex task, and to detect patterns in a sequence of seemingly random numbers. It solved the problem in 3 minutes and 20 seconds. They estimate that it will have the same problem, it would be 10,000 a year for a Top supercomputer is the most powerful in the world today is to solve the problem.

“This is a dramatic increase in speed compared with any known classical algorithms, and an experimental realization of the quantum will be great for this particular computational task, and a precursor of a much-anticipated computing paradigm,” wrote the research team, led by Google, the AI ‘ s, Frank Arute.


While the peer-reviewed research, and has drawn applause, and with the MIT’s William D. Oliver, and compare them with the findings of the Nature of the Wright brothers ‘ first flight, the skeptics say, that Google’s sale of its performance.

Researchers at IBM’s (IBM.N), which is the most important of Google’s quantum computing, the main rival, said a super-computer with additional hard disk storage can solve the random number problem in the majority of the 2-1/2 days, with greater precision and accuracy.

She also said that Google has threatened to mislead the public by implying that the new-style machines that would replace the existing one.

“Quantum computers will never reign supreme over the classical computers, but to work in concert with them, as each has their own strong points,” Dario Gil, director of research at IBM, wrote in a blog post here
