Quantum Computing, Qubits and Quantum Computers -Definition and Applications

What is quantum computing

Experts believe that the next revolution in the field of information science will be run by quantum computing because most powerful traditional computers cannot handle the information and fulfill those tasks. What is quantum computing, what are its applications, and what are the most important constraints in its development?
It is simply a new way of designing microprocessors based on the laws of quantum physics. To understand the leap that will be made in the development of quantum computers, one must look at how the traditional computer works.

This system is based on a binary system with one of the values of either zero or one. Each value is known as a bit. This system adopts the same logical rule as the state of a light bulb, for example, it either shines (one) or does not light ). There is no third case that can have a lamp. Using dual logic, the ordinary computer stores, and processes information, and as more and more information storage and processing capacities are needed, traditional computers - including giants - have shown their limited potential when it comes to complex issues that require massive and complex information processing.

Quantum Overlay

Since the 1980s, computers have been developed using a different logic that is not subject to the laws of classical physics but to the laws of quantum physics that apply to nanoparticles.
According to these laws, the information storage box can take three values (zero) or (one) or both at the same time, that is called qubit or qbit, if the lamp was small and the laws of quantum physics apply, luminous or non-luminous or in both cases at the same time.

This third case is called quantum overlay, one of the characteristics of quantum physics that Schrodinger represented in the cat experiment, in which he proved that the "quantum cat" can be both alive and dead at the same time.

It is this strange behavior of matter when it is nanoparticle that will give quantum computing in the future its supernatural ability to perform calculations and processing huge information compared to traditional computers. For example, quantum computers will be able to decode any encryption system currently used to protect information in moments, while the most powerful supercomputers today may take years to decode.

Areas of use

Quantum computing applications - for example, will lead to solutions to complex equations that enable the manufacture of superconductivity at normal temperature, which will allow the development of new technologies such as high-speed magnetic trains and the transmission of electricity at long distances without waste.

Quantum computing will also enable the design of intelligent networks for the exchange of high-efficiency information using one of the properties of quantum physics, quantitative interconnectivity. This strange feature is to "connect" two bodies quantitatively so that one can recognize the state of one by observing the other even if it is at a distance, which means that the information will not be transferred, which expose them to the possibility of piracy, but it will be  simultaneously exchanged for this technique, also known as remote data transfer.

In general, quantum computing will be an effective tool for achieving important scientific and technological leaps by opening up vast possibilities for manipulating large data, understanding natural phenomena and accomplishing complex tasks by making calculations that are extremely complex or impossible in time recording compared to today's most powerful supercomputers.

The new method to track unobserved quantum particles

Secret movements

The basic principles of the quantum theory include that quantum objects are present in the form of waves or molecules, but are not actually in fact until they are subject to measurement. Identification and tracking of quantum objects are not under observation, but scientists have recently encountered this problem and have proven the possibility of tracking "uncontrolled quantum particles".

The team of researchers from Cambridge University demonstrated the ability to track uncontrolled or unobserved quantum particles instead of measuring the quantum body itself while testing how quantum objects interact with their environment.

Molecules can trace their environment during their movement, and any contact or interaction with the environment that can encode information within those molecules. The researchers have developed a way to map these interactions without having to monitor them directly. In pursuing these interactions, they discovered their ability to decipher that information from the molecules at the end of the experiment after observing the molecules, allowing them to closely track the movement of quantum particles and observe their behavior.

The forbidden domain

The new method of tracing uncontrolled quantum particles may allow scientists to test old predictions in quantum mechanics. It includes ideas such as the possibility of a molecule in two places at once, or applications such as "mental telepathy," in which information travels between people without the passage of molecules between them.

This research not only proves what was previously impossible in the physical world but also helps scientists to investigate the possibility of psychotropic psychosis. More importantly, it helps to expand scientists' knowledge of molecular waves, previously thought to be pure computing tools used to predict the results of quantum experiments only. During their experiment, researchers discovered the direct correlation of coded information in quantum molecules after each waveform interaction. They have claimed that the results of the study suggest a close correlation between the wave function and the real state of molecules, and they have discovered the prohibited scope of quantum mechanics: stabilizing the path of quantum particles in a period where they are not monitored.

Can we really determine and predict that the black box we bought is capable of performing real quantum operations, and will it be some classical simulation not only in a good way? When quantum computers come to the market, how will the buyers know that they are not copying or settling for something which is not enough in the form of "quantum"?

This is not just a hypothetical question. In the last few years, many physicists have made big progress in the field of quantum computing, but they are looking for an answer to this question.

Although there are many models of commercially available new quantum computers, it is not easy to identify and answer this question.
A physicist in the Department of Mathematical Informatics in Nagoya, Mr. Francesco Busemi said, "Classical computer uses bits to store information. Each bit can be in one of two states: 1 or 0 to store information. "The position of a qubit may depend on the condition of another class, even if both are separated from long distance, in this way the classical theory experience explained by us, we have so far experienced "no quantum computer can perform better on the device on which you are still reading this article, but the day is coming - and coming soon. There are many scientists working on this topic, we think that it is possible to create a platform for creating real-time quantum computers.

Mr. Buscem asked, "Now what is clear is that quantum computers will never completely replace the classical people, which will probably create the most versatile machines to interact and help classical computers to solve some specific quantum computers. What to do-though practically relevant problems? Before going far away from the possibilities of quantum computing, Come back to the question - How can you differentiate between a real quantum computer and a motivator? 

Qubit-based computers will already be able to perform classic computers seriously in important areas, although they do not have the possibility of having a personal computer. Any computer, quantum or classical, should be able to obtain, store, process and output information. The key to the power of the quantum computer is in the quantum nature of qubits that stores information. But it is also where imposters can infiltrate. Classical computers can obtain quantum inputs, measure them, classify measured values, process stored information, and output information.

Mr. Buscemi explained, "Quantum computers have many approaches, which include quits based on the properties of electrons, quantum dots, photons, and other things. It is clear that a" standard "quantum computer will not be, in short, quantum computing. The landscape is developing very rich and diversified, in which no other machine can perform better in other work. The challenge is to keep such a wonderful garden under control, preventing it from transforming into an incredible forest, to help save the garden, but to help prevent the jungle, it is the inspiration for this new research. The first step in developing these standards for Quantum was to demonstrate that they are actually in. He noted that the tests are all-inclusive - the real quantum computer is always nearby. And the imposters will always fail - and they are also experimental viable. To demonstrate that they should not be rejected, regular old computers have played an important role in designing practical tests. (3)

Quantum computing will be the main tool in the future to simulate natural phenomena, anticipate weather and air disturbances with high accuracy and understand chemical and molecular reactions, enabling the development of new and effective medicines, DNA analysis and early detection of cancer.
The way of quantum computing is not without the difficulties that have delayed and will delay the day when we will see the quantum computer in the markets. These barriers are mainly technical obstacles. First, providing a stable and suitable environment for the computer is approaching the absolute temperature of about 273 degrees Celsius.

The second major obstacle is to maintain the quantitative stability of the computer. The more it's capacity, the lower its stability. Therefore, part of its processing capacity will be directed first to monitor the stability of the computer. All these obstacles make many specialists in this field and do not expect access to the manufacture of quantitative computer and display in the market.

On the other hand, others believe that it may not take a few years before we see these computers on the market. In either case, there is great concern about the use of quantum computing to violate the privacy of users of traditional information networks, especially in the transition period when using traditional and quantitative technologies at the same time, which may last long, the current safety procedures - including encryption techniques - would be of no use to a quantum computer.
