Hello everybody! The topic of my presentation is a quantum computer. I would like to tell you, what exactly it is and when you can has one. And why each one needs in quantum computers.
So, most of modern people have a computer. We have a powerful machine and everybody uses it for many reasons: for entertainment, for working, for chatting and many others.
We live at the age of Big Data. The amount of information grows every year, day, every second. Phone calls, climate data, social media, movie, music – these all store in computer. Besides, scientists needs in calculating machine for solving problems of modern science (and some of them are impossible to calculate). And we need more and more power for it. Unfortunately, power of our computers is limited. So, it is the end?
Yuri Manin and Richard Feynman do not think so. In 1980, Yuri Manin, a Soviet mathematician, proposed an idea of quantum computing based on quantum mechanical phenomena, such as superposition and entanglement.
(These words are not scary. It is simple. When an electron can be there and there at same time. It is a superposition. When you determine one of two electrons, you can determine another at same time. It is an entanglement. )
In 1981, a great American physicist Richard Feynman proposed a basic model for a quantum computer, but theoretically. Today, development of quantum mechanics and technology allows to us to create a real model for quantum computer.
Ordinary computers compute on a binary system of zeros and ones called bits. But quantum computers are far more powerful, they compute on quantum bits or qubits. There are a number of physical objects that can be used as a qubit: a single atom, ions, single photon or an electron. But how it does works?

Quantum computer can crack every security code. And with quantum computer the idea of encoding system is lost.
• Calculation experiments for new physics theory.
Quantum computer can help in solving problems of modern physics. Such as, a vacuum state, a string theory and others.
Of course, these are great abilities. Creation of quantum computer must be a major problem in the world of science. Moreover, some types of quantum computer are building. Actually, the small Canadian company D-Wave System demonstrated the first 512- qubits quantum computer.
Today, theory of quantum physics is developing extremely fast. It makes it possible to create a powerful quantum computer, which can change our life, as a classic computer did. Imagine, you can modeling and calculate everything, you can know everything. And it is really close future or nowadays, will see.
I hope to bridge the gap between computer science and physics by researching quantum computing. This rapidly-growing field has already produced unprecedented
The novel, Alice and Quantum Land, by Robert Gilmore is an adventure in the Quantum universe. Alice, a normal teenage girl, goes through quantum land and understands what quantum is and how it works. The quantum world is a difficult one to understand, as its nature is one of complex states of being, natures, principles, notions, and the like. When these principles or concepts are compared with the macro world, one can find great similarities and even greater dissimilarities between the world wherein electrons rule, and the world wherein human beings live. In Alice in Quantumland, author Robert Gilmore converts the original tale of Alice in Wonderland from a world of anthropomorphic creatures into the minute world of quantum mechanics, and attempts to ease the reader into this confusing world through a series of analogies (which comprise an allegory) about the principles of quantum mechanics. Through Alice’s adventure she comes across some ideas or features that contradict real world ideas. These ideas are the following: Electrons have no distinguishing spin, the Pauli Exclusion Principle, Superposition, Heisenberg Uncertainty Principle, and Interference and Wave Particle Duality.
The study of neurobiology has long involved the actions and interactions among neurons and their synapses. Changes in concentrations of various ions carry impulses to and from the central nervous system and are responsible for all the information processed by the nervous system as a whole. This has been the prominent theory for many years, but, now, there is a new one to be reckoned with; the Quantum Brain Theory (QBT). Like many new theories, the QBT has merits and flaws. Many people are wholeheartedly sold on it; however, this vigor might be uncalled for. Nevertheless, this could prove to be a valid and surprisingly accurate theory of brain function.
Quantum Mechanics is a branch of physics that describes the structure and behavior of matter.
A very famous example of such a project is the Deep Blue. Deep Blue was the machine who beat Garry Kasparov at chess. It is one of the cornerstones of the advances that have happened in the field of Artificial Intelligence.
Soon after his public schooling Turing began working on his undergraduate at King’s College. Here he became interested in the readings of Von Neumann’s quests into the logical foundations of quantum mechanics. Through these readings Turing was believed to structure his thinking from the emotional states that he had been suffering from to a more valid form of thought.
As you can imagine, since quantum entanglement is a faster than light connection and communication that isn’t stopped by any distance, it can accomplish some pretty amazing tasks. For example, it could introduce faster than light and un-hackable communication. Since one particle can affect the other particle faster than light, all we have to do is figure out how to put information in on one end and see it be received on the other. And since entanglement doesn’t use any sort of internet, it can’t be hacked. This would be a huge advantage in wars and even just cyber safe phone calls. Also, faster than light internet could be introduced. If this were to come along then everything would be a million times easier to do, and you would accomplish a lot more faster. Next, quantum entanglement helps prove the many worlds theorem. This theorem states that all possible alternate pasts and futures are real and existing. Last, quantum entanglement can theoretically connect across time, so maybe in the far future we might be able to send information into a future time. So, quantum entanglement, if used properly, could be used for amazing things that would highly benefit the life of now-a-day humans and maybe even future
In March, Einstein creates the quantum theory of light, the idea that light exists as tiny packets, or particles, that we now call photons. Alongside Max Planck's work on quanta of heat, and Niels Bohr's later work on quanta of matter, Einstein's work anchors the most shocking idea in twentieth century physics: we live in a quantum universe, one built out of tiny, discrete chunks of energy and matter.
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
The discovery that we can make photons act strongly together could make developing quantum computers a lot easier. this discovery is the most recent of the five having only happened last year. Normally photons don't interact “Getting photons to stick together is not easy because they normally pass through each other without interacting”(Johnson), but...
In the final analysis, quantum specimens both conceptual, entity, and particles are what sustain human life. Without some time of mystery and amusement humans would never seek to make innovations. Without innovations society would begin to stagnate into a pig sty of rituals. If one society were to collapse, then others would soon follow. This collapse of society is the true Armageddon, the failure of all supernatural quanta to act with normal quanta. Hence the important of quantum physics, it is necessary for life, society, and humanity.
There are still limitations in classical cryptography, it is purely mathematical and information cannot be separated from its physical representation. In Classical physics, we use binary form to store and process the data. In the 1980s, C.Bennet, P.Benioff, R.Feynman and others observed that new and very powerful ways of information processing are possible with quantum mechanical systems. This gave birth to the concept of quantum computing.
Quarks have become important pieces of matter that have allowed us to further our knowledge of what everything is made of. Quarks are the smallest objects in the universe and they along with leptons make up all pieces of matter. Research done on quarks has allowed us to better understand the particles they form. As research continues in quarks one can only imagine the possibilities for further research that can be done based off of our knowledge of quarks. Our knowledge of quarks may very well be the key to understanding our universe.
In the past few decades, one field of engineering in particular has stood out in terms of development and commercialisation; and that is electronics and computation. In 1965, when Moore’s Law was first established (Gordon E. Moore, 1965: "Cramming more components onto integrated circuits"), it was stated that the number of transistors (an electronic component according to which the processing and memory capabilities of a microchip is measured) would double every 2 years. This prediction held true even when man ushered in the new millennium. We have gone from computers that could perform one calculation in one second to a super-computer (the one at Oak Ridge National Lab) that can perform 1 quadrillion (1015) mathematical calculations per second. Thus, it is only obvious that this field would also have s...
The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the “Calculating Clock,” as it was often referred to as, “performed it’s operations by wheels, which worked similar to a car’s odometer” (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming “the first analog computer of the modern ages” (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfried Leibnez improved Pascal’s model by allowing it to also perform such operations as multiplying, dividing, taking the square root.
