Quantum computers – Quantum supremacy of google

According to the Financial Times, Google’s quantum computer(quantum computers) was able to achieve Quantum Supremacy for the first time. This quantum computer can perform calculations that take ten thousand years for a supercomputer like IBM Summit, which takes ten thousand years to solve in 3 minutes.

Google is wrong to claim it has reached a turning point in the history of computing by being the first to achieve “quantum supremacy”, according to researchers at IBM.

In a paper published on Monday, five researchers at the US computer maker said Google had overstated a claim that its system, built using the principles of quantum mechanics, could far surpass even the world’s most-powerful supercomputer.

Google’s claim was contained in an unpublished research paper first disclosed by the Financial Times last month. It has been hailed as a big step in the development of quantum computers, which have the potential to solve problems in materials science and other fields that are far beyond traditional computers.


The last Google Quantum Computer(2019) has 53 functional qubits, and if the number of these qubits increases in the future, the power of this computer will increase exponentially. In such a way that such a tool will be able to crack Internet encryption and read different types of encrypted code! Until then, however, there is a long way to go.

In fact, quantum superiority means that a quantum computer can perform calculations that cannot be calculated in a reasonable amount of time. In March 2018, Google sensational 72 -qubit quantum Bristlecone unveiled her and hoped to use it to gain a lead quantum. Now the company’s researchers have been able to achieve their goal using this chip.

Such an achievement is valuable because, for the first time in history, it performs computations that no ordinary computer can solve, and so the term quantum superiority can be used. In fact, the calculation time of ten thousand years is not practical for any computer and it can not be considered possible.

The article of this research states:

This increase in speed over all classical algorithms provides an example of the experimental realization of quantum superiority in computational applications and promises the emergence of a predicted computational model.

The team also saw quantum excellence as a turning point in achieving full-scale quantum computing. Researchers point out in their paper that such a result could be an example of a violation of Moore’s Law and show that the power of quantum computers increases exponentially rather than linearly.

Google researchers have stated in their article that with the new technology, they have reached the border of “quantum superiority”. What Google researchers have called “quantum superiority” is a type of computing that can surpass the example of classical computers by distance.

In fact, in classical computers, each unit of information called a bit has a value of zero or one. But in a quantum computer, each bit can be zero and 1 at the same time, and this allows for multiple and simultaneous computations.

If quantum computers are built on a large scale, then it can be said that gigantic achievements will be achievable by humans and the frontiers of human knowledge and progress are expected to collapse one after another. This is due to the advanced capabilities of these computers.

In fact, quantum computers can calculate and calculate millions of states of a problem in a fraction of a second. This has not been possible in mathematics, chemistry, physics, and biology.

Google has declined to comment further on quantum computers since the leak.

Despite these brilliant results, quantum computers still have a long way to go before they can replace ordinary computers. Of course, whether quantum computers can be a real replacement for PCs and desktops is another question that can only be answered in the future.


Google’s claim to have demonstrated quantum supremacy—one of the earliest and most hotly anticipated milestones on the long road toward practical quantum computing—was supposed to make its official debut in a prestigious science journal. Instead, an early leak of the research paper has sparked a frenzy of media coverage and some misinformed speculation about when quantum computers will be ready to crack the world’s computer security algorithms.


About KSRA

The Kavian Scientific Research Association (KSRA) is a non-profit research organization to provide research / educational services in December 2013. The members of the community had formed a virtual group on the Viber social network. The core of the Kavian Scientific Association was formed with these members as founders. These individuals, led by Professor Siavosh Kaviani, decided to launch a scientific / research association with an emphasis on education.

KSRA research association, as a non-profit research firm, is committed to providing research services in the field of knowledge. The main beneficiaries of this association are public or private knowledge-based companies, students, researchers, researchers, professors, universities, and industrial and semi-industrial centers around the world.

Our main services Based on Education for all Spectrum people in the world. We want to make an integration between researches and educations. We believe education is the main right of Human beings. So our services should be concentrated on inclusive education.

The KSRA team partners with local under-served communities around the world to improve the access to and quality of knowledge based on education, amplify and augment learning programs where they exist, and create new opportunities for e-learning where traditional education systems are lacking or non-existent.
