Quantum computing between reality and theory - Al-Watan newspaper

The world has witnessed an amazing development in information technology in all fields, which has provided the opportunity for the speed and accuracy of making the right decision at the right time. Among the most important of these areas are the complex mathematical operations that take place through the computer we know, which is now called the classic computer. Due to the abundant flow of daily information, it is difficult to perform the calculations needed by the person or organization concerned quickly, with high accuracy, and more securely, so that they cannot be hacked. Based on these data, the major international companies in the field of computing compete in the production of what is called today “quantum computing” or “quantum computer”, which will have an impact on revolutionizing the fields of machine learning. Ken Olsen, CEO of one of these companies, predicted in the 1970s that “there is absolutely no reason for anyone to have a computer in their home.” Ken Olsen based his opinion on the cloud computing model where computations depend on remote servers. Keene's prophecy has been fulfilled as our world is now increasingly moving on cloud computing. The question now arises, are quantum computers manufactured with the same technological processes as a classical computer? There are two classes of quantum computers, one of which is based on the use of superconducting units, which are made using integrated circuit technology from niobium and aluminum, under very low temperatures. The other class, using silicon photonics, generates superconducting entangled photons. IBM recently came up with an experimental 20-kilobyte quantum computer. As for the language used in the quantum computer, it is a language similar to the programming language known as the “C” language, “which makes it unique in its ability to recognize the classical data used by the classical computer and stored in the “0” or “1” and the quantitative data stored in the “ 0 and the “1” at the same time, which is called a “qubit.” The reader may ask: Are there quantum computers produced now? The answer is, yes, there are basic quantum computers in many labs around the world. For example, Microsoft, IBM, and Google are developing their devices by making huge investments in this field. There are also quantum computers available to the general public, built by a Canadian company called D-Wave, at a cost of $15 million. On the other hand, the information circulated through a quantum computer is more secure than a classical computer, simply because once the calculation is done, the Destroying the circles in which the operation took place, and accordingly, there is no information stored on it, and therefore no information can be obtained using any infiltration program. The difficulty in quantum computer production is how to create them under very low temperatures and then measure them, destroy them and replicate them to perform other operations. Finally, it can be said that quantum computing technology has the potential to change the dynamics in military affairs, trade, and the strategic balance of power, as governments of different countries take action. Initiatives to expand exploratory research on quantum computing technologies to develop and create solutions. Quantum computing also aids energy processing and transmission, and will be able to solve complex problems faster than modern classical binary supercomputers. Major technology giants around the world are investing more resources and increasing their investment in research and development, with the aim of taking advantage of the commercial opportunities of quantum computing in the government and private sectors.* Department of Mathematics - College of Science - University of Bahrain
