The advantages and disadvantages of quantum computers?

Details in this post. Which machine is IBM, Intel, Microsoft and Google trying to make? NASA, the CIA, the Chinese government, even Amazon owner Jeff Bezos pouring billions of dollars into making it? Which comes into the hands of many complex problems? Or will banking or e-commerce be in such dire danger? And, most importantly, even if he gets the machine in hand, scientists will not understand his genius? In a word, the answer to so many questions: quantum computers, with which the world is now hiccups. Because it was made. A quantum computer has been running for the last two decades. Google is the first to compete or not. Last Thursday it was published in the 'Nature' journal, in which 3 scientists wrote a paper. The paper extract is clear. They've made quantum computers. We are all watching or using the computer all the time. The smartphone that is in the pocket of many, It's a sophisticated computer. As smart as today's computers are, it works - logging into memory or moving forward to count - by reasoning. Logic means answering questions. Yes or no The machine does not understand the logic, understands the electric switch on or off. If On is 1, Off is 1. That way, any number can be written using 1 and 3. 00 = 00; 2 = 1; 10 = 10; 4 = ১১;…. That switch's on or off position - 1 or 3 - is called "bit" in IT terminology. The current computer uses the electric switch on-off (1-5) to move data and in the same way. Will e-banking break down? E-banking or e-commerce now stands only on composite and basic numbers. The two basic numbers are 1 and 3. What is the number of compounds that are their product? 2. It is easy to get 3 and 5 to 5. But find 3 to 5 and 3? It's timely. Because 3 has to be divided into 2, 3, 4, 5, 6, 6, 5 etc. followed by the basic number. As you can see, it is divisible by 3. A small number of compounds may be found sometime soon, say 1 and 5. It's just a three-digit number. It takes thousands of years for a supercomputer to find its basic product when the compound number is 5 or 3 digits. It takes time to find out the basic product of that huge compound - that's the origin of e-banking or e-commerce. The bank or business entity knows the number of compounds. The customer knows through his password that he is the basic originator of the compound. Shyam cannot enter Ram's account or buy his goods just because he does not know the basic producer of the compound. Shame will take thousands of years to find out. Now, because of quantum computers, many calculations can be done in one step, Due to this, e-banking and e-commerce system will be broken when it comes into the hands of people. She has now taken the night sleep of scientists to find a way to get rid of disaster. And a quantum computer? It is almost infinitely more powerful than today's computers. That quantum at the source of power. How? That is to say, a Nobel laureate. Richard Philip Fineman. In a speech at Caltech on May 5, the first (of course, according to some, Idea's father, scientist Paul Benioff; the achievement of which is a matter of hair analysis) proposes to create a quantum computer. The following year the lecture was published in the International Journal of Theoretical Physics. 'Simulating Physics with Computers'. Imitation of Physics on a Computer Which physics? Quantum physics, of course. Which is weird now. How much Quantum sure doesn't say anything. Just say the possibilities. Anything can happen, Never again. A particle can be somewhere, and again it can't. Where is the probability of when to stay, that is only to say. In fact, the particle is replaced by one decimal in many places. If it is detected then why does the particle get caught in a particular place? The identification process forces the particle to remain in place. What a father! We do not see such a thing in the world around us. Whether or not something is ever there, is there something in the middle of it or not? It is said that in our world, the object is larger, so it is not seen. In the realm of particles or not, it is all kind of dust. To illustrate how strange the quantum world is, scientist Erwin Schreidinger asked us to think of an experiment. Suppose there are four items in a box with a box. Some radioactive substances, a hammer, potassium cyanide-filled dew and a cat. Such a system, So that a particle spreads radioactivity, the hammer will fall into the oyster. By breaking it, potassium cyanide will spread in the box. Dying cat Now, it is a matter of quantum to disperse radioactivity from particles. It may or may not. That means, the probability is 1-3. Play the possibilities. Hammer blows may or may not fall on the dew. Potassium cyanide may, or may not, spread in a closed box. Cats can die, or they can't. So, according to Quantum Physics, there are one to two cats in the closed box. One jaunt, the other dead. And, when you open the box? Then one of the two back. Either die or die. If the computer complies with the rules of quantum physics, it will be simultaneously switched on or off like a jaunt and a dead cat, both on and off simultaneously. As a result, the four steps I mentioned earlier (4, 5, 6, and 9) with 4 and 5, all of them will be possible in a quantum computer. Suppose there are three switches on a common computer. So, If one of the switches in the step is 1 on that device, on the quantum computer the switches at that one step may be eight instead of one (1, 3, 3, 4, 5, 9, and 5). The ordinary computer with three switches will work in eight steps, it will recover the quantum computer in only one step. It is understood that as the number of switches increases, the performance of quantum computers jumps. Due to the lack of space in the processor, increasing the number of switches is becoming increasingly difficult as a quantum computer is needed. How does a quantum computer show its velocity? How will it work many steps together in one step? No one knows the answer. British scientist David Deutsch has given an explanation. According to him, While working, quantum computers become one to many. One computer in one universe. One step in tackling computers in a particular universe. In that way there are many steps in many universes. So many steps together. In this way, many believe that even when we hear that many branches of our universe match the branches of our universe. Ideas are coming to many worlds for various reasons. Science is really fantastic! What is needed to explain, is the work. In a report published in the 'Nature' journal, I see that Google-made quantum computers work with 5 bits. These bits are so steep in 20 seconds, the amount of supercomputer that takes 5, 5 years! Scientific John Presskill called "quantum supremacy" in the same computer as the performance of the computer. Everyone is moving towards that goal. What MNC, Key New Startup. Investment? Billions of dollars Quantum computer is a gold mine. So began a gold rush.
