While creating, maintaining, and programming a quantum computer is challenging, quantum computers are able to yield results from computations that are too complex for classical computers. In order to understand the benefits and challenges one must understand what a quantum computer is; and the difference between classical and quantum computers. Classical computers use bits; a bit can be represented as either 0 or 1. Vedral states that the value of a bit in computing is determined by the electrical charge being passed through the bit; 0 being the absence and 1 being the presence. The bits are physically represented each by their own transistor; when used in combined computation, logical statements can be used. The rate at which bits are switched …show more content…
Being that qubits are usually represented at atomic or subatomic particles, they can be rather difficult to manipulate because of their size and physical properties. Because of the natural attraction and repulsion properties of most atomic and subatomic particles, if one particle is manipulated, the particles around it may also be affected; therefore as the amount of qubits on a chip increase, the more of a probability there is for error. O’Carroll analogizes this phenomenon as if there was a garage door opener that would open every garage on the street. Holger Buch, a doctoral candidate of UNSW and lead author for quantum computing describes this manipulation as “daunting” (O’Carroll). According to Hecht, quantum information is fragile, so fragile that the information cannot be read without destroying it (111-112). Therefore, if the information will be destroyed upon reading, one can only read information once. The only way to retrieve that information if lost is to conduct the same computation again. While conducting the same computation again on a classical computer is no problem, it may be a problem on a quantum computer due to its current instability and its likelihood of error. Because of all the errors and issues with stability, as of now there aren’t any quantum computers that hold many qubits as compared to classical computers. Classical computers such …show more content…

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.
Nanotechnology is the manipulation of structures at nano levels. It uses incredibly small materials, devices, and systems to manipulate matter. These structures are measured in nanometers, or one billionth of a meter, and can be used by themselves or as part of larg...
Mark Baker adopts a variety of text types and multiple voices in The Fiftieth Gate in order to allow his responder to view his parents’ experiences from a multitude of ways. Baker as a historian, embraces the memory of his parents in his exploration of the past. The examination of records, facts, interviews and statistics allows one to gain an understanding of specific details, as well as providing a context for the human story. Instead of focusing on historical sources, Mark Baker focuses on giving a perspective which reflects his family as much as their family history. The utilisation of the various voices and text types emphasise the complexity of unraveling the past and marks his progression along the journey through the gates. Through
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.
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 website for Princeton University’s Computer Science department offers a great analogy of the subject, “What energy is to physics, information is to computer science.”
Chapter 1 Quantum Neural Network 1.1 Introduction and Background The eld of arti cial neural networks (ANNs) draws its inspiration from the working of human brain and the way brain processes information. An ANN is a directed graph with highly interconnected nodes called neurons. Each edge of the graph has a weight associated with it to model the synaptic eciency. The training process involves updating the weights of the network in such a way that the network learns to solve the problem.

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...
Von Neumann architecture, or the Von Neumann model, stems from a 1945 computer architecture description by the physicist, mathematician, and polymath John von Neumann and others. This describes a design architecture for an electronic digital computer with a control unit containing an instruction register and program counter , external mass storage, subdivisions of a processing unit consisting of arithmetic logic unit and processor registers, a memory to store both data and commands, also an input and output mechanisms. The meaning of the term has grown to mean a stored-program computer in which a command fetch and a data operation cannot occur at the same time because they share a common bus. This is commonly referred to as the Von Neumann bottleneck and often limits the performance of a system.
It was pure joy to learn how the Boolean logic makes computers work. In my undergraduate studies I took up courses in Software Engineering, Computer Networks, Data Structures, JAVA, Operating Systems, Computer Graphics, Design and Analysis of Algorithms, Database Management, Web Technology and Mobile Application Development. Practical application aspects were introduced to me through laboratories corresponding to the subjects.... ... middle of paper ...
The date is April 14, 2035 a young woman is woken up by the silent alarm in her head. She gets up and steps into her shower where the tiles sense her presence and calculate the water to the precise temperature that she likes. The news flashes in her eyes announcing that today is the tenth anniversary of the day quantum computing was invented. She gets dressed and puts on her favorite hat with a smartband embedded in the rim, allowing her access to anything she needs just by thinking it. Her car is waiting with her trip preprogrammed into it. She arrives at the automated airport to see her associate waiting for her. By the look in his eyes she can tell he is doing a quick online search in his mind. Technology is constantly growing and soon this future will be a reality.
