vie for quantum revolution

In the future, quantum computing will change the map of our digital world. We will be able to do many new things. Such as making or prototyping medicines or delineating ways to ensure less fuel use. With the help of quantum computers, the way to solve the most complex problems will be found.

The US and China are vying for the development of a quantum computer that will change today’s digital world. This will be the same kind of revolution in the field of information technology as the computer has come. The US has invested about 250 million dollars in one hundred and eighteen plans. On the other hand, the Chinese government is developing the National Laboratory of Quantum Information Science in Hefei. It was only two years ago that China launched the first quantum communication satellite. China is also setting up a secret communications network in Jinan province. The rivalry of the world’s two major economic powers in the field of quantum information shows its importance. Actually this technology will be so powerful that it will change the world.

Scientists from many countries including India are trying to make quantum computers. In the digital age, the one who has the data is the most powerful. The specialty of a quantum computer is that it will increase the speed of data analysis millions of times. It can store as much data as possible in the least amount of space and can make computational techniques more efficient. This will also reduce energy consumption. Today, many multinational companies including Microsoft, Intel, Alphabet-Google, IBM, D-Web and governments of different countries are spending a large part of their defense budget on this campaign to make quantum computers.

According to the physicist Niels Bohr, ‘If quantum physics had not pushed you deeply, you would not have understood it.’ The world is completely different at the quantum level. Here everything happens completely contrary to our common understanding. It is not a simple world of zero or one, but a place where there are strange positions of both zero and one. Is it possible in our world that we toss a coin and both head and tail come together! With quantum computing, we enter a world in which many parallel computations can be solved simultaneously.

At present it is a big problem to get some necessary information in a short time from a huge collection of data. Quantum computers can do this complex task very easily. For example, if we were to search for information about one person out of a million social media profiles, a traditional computer would look at all of those million people’s information and go through a million steps. Whereas a quantum computer can deal with it only in a thousand steps.

Its most important feature is its speed. It can single-handedly perform tasks performed in parallel by multiple conventional computers at the same time. A number of encoding systems are used in these computers to be used in banking and security applications, which are unable to solve mathematical problems to a certain extent. Quantum computers can overcome these shortcomings. Apart from this, they can also be useful for scientific research, astronomical space missions, data protection etc.

Two years ago, the uncrowned king of the Internet world, Google, had told that the world has reached the quantum age. Accidentally in September 2019, an article published in the science research journal ‘Nature’ was leaked online. From this it was revealed that Google has developed a quantum computer called ‘Sycamore’ which is capable of doing twenty thousand lakh crore calculations in a second. Later, Google also claimed that Sycamore was able to perform calculations in just two hundred seconds that would have taken ten thousand years to do the world’s fastest supercomputer ‘Summit’. How much truth was there in this claim of Google, it is not yet known. But there is no doubt that even ordinary quantum computers will be millions of times faster than today’s supercomputers.

According to experts in quantum technology, quantum technology has the potential to revolutionize the analysis of information. All information is entered coded as zeros and ones. But in the 1960s it was discovered that the place where this information is kept can affect its use. This means that we can store information on a computer chip, as we do today, but we can store zeros and ones in other very subtle places, such as in a single atom or even in smaller ones. in molecules. According to Chinese scientist Alechandro Pozas, these atoms and molecules are so small that other rules also determine their behavior. The laws that determine the behavior of atoms and molecules are the laws of the quantum world.

Until a few years ago, quantum computing was nothing more than a theoretical fantasy for scientists. But the whole scenario changed in the last two years. The pace of progress in this direction can be gauged from the fact that not a complete quantum computer, but its processor or central processing unit (CPU) has been introduced in the market. Recently a Dutch company Quantware has introduced the world’s first Quantum Processing Unit (QPU). The name of this superconducting processor is soprano. This is nothing short of a miraculous achievement in the forty-year history of quantum computing. However, on the basis of what has happened in this area so far, it can be said that China has taken its lead in this race.

In 2016, China announced the launch of the world’s first quantum communications satellite, claiming that it could communicate with it in encrypted signals that no other country could read. Through these experiments, China not only proved the concept of quantum technology, but it also showed that it has the capability to do so. The use of quantum technology will create thousands of new possibilities in areas such as health and science, security, drug manufacturing and industrial manufacturing. In the coming times, intense competition can be seen in this direction.

In the future, quantum computing will change the map of our digital world. We will be able to do many new things. Such as making or prototyping medicines or demarcating pathways to ensure less fuel use. With the help of quantum computers, a way will be found to solve the most complex problems. But most of the governments are interested in using them in the defense sector. Such as establishing extremely secure communications or detecting enemy aircraft. The major concern about quantum computers is how to solve its secret encoding. So far encrypted signals are considered reliable in terms of data security. Quantum computers will make this task easier.
