A concise, "no-frills" introduction to quantum computation and quantum cryptography for non-experts. Rather than concentrating on stories about scientists and philosophical concepts, it provides a step-by-step approach to quantum information. Starting from the idea of quantum cryptography, it presents the basic principles of quantum mechanics and explains how this can be used to make cryptography absolutely secure against eavesdropping. Subsequently, the most important quantum algorithms are explained and technical problems in realizing quantum computers are discussed, followed by a presentation of recent experiments -- some of which are found here in a textbook for the first time. Easily accessible for undergraduates and graduates -- especially those studying subjects other than physics -- who need an introduction to this rapidly developing topic.

A Science journalist reveals the existence of the world's first quantum computer--created by a team of Silicon Valley researchers and able to simultaneously compute all possible solutions to a problem, making it the most powerful computer in the world.

An accessible introduction to an exciting new area in computation, explaining such topics as qubits, entanglement, and quantum teleportation for the general reader. Quantum computing is a beautiful fusion of quantum physics and computer science, incorporating some of the most stunning ideas from twentieth-century physics into an entirely new way of thinking about computation. In this book, Chris Bernhardt offers an introduction to quantum computing that is accessible to anyone who is comfortable with high school mathematics. He explains qubits, entanglement, quantum teleportation, quantum algorithms, and other quantum-related topics as clearly as possible for the general reader. Bernhardt, a mathematician himself, simplifies the mathematics as much as he can and provides elementary examples that illustrate both how the math works and what it means. Bernhardt introduces the basic unit of quantum computing, the qubit, and explains how the qubit can be measured; discusses entanglement—which, he says, is easier to describe mathematically than verbally—and what it means when two qubits are entangled (citing Einstein's characterization of what happens when the measurement of one entangled qubit affects the second as “spooky action at a distance”); and introduces quantum cryptography. He recaps standard topics in classical computing—bits, gates, and logic—and describes Edward Fredkin's ingenious billiard ball computer. He defines quantum gates, considers the speed of quantum algorithms, and describes the building of quantum computers. By the end of the book, readers understand that quantum computing and classical computing are not two distinct disciplines, and that quantum computing is the fundamental form of computing. The basic unit of computation is the qubit, not the bit.

This self-contained 2006 text introduces the principles and techniques of quantum cryptography, with specific focus on secret-key distillation.

A breath of fresh Quantum Computer air. A Quantum Computer (also recognized like a quantum supercomputer) is a calculation implement that produces straight employ of quantum-mechanical occurrences, such like superposition and entwinement, to accomplish transactions on information. Quantum Computers are dissimilar as of digital computers founded on transistors. Whereas digital computers need information to be encrypted in to binary numerals (bits), Quantum Computation utilizes quantum assets to constitute information and accomplish transactions on those information. A hypothetical model is the quantum Turing engine, as well recognized like the general Quantum Computer. Quantum Computers share hypothetical resemblances with non-deterministic and likelihood computers. One illustration is the capacity to be in further compared to one state concurrently. The area of Quantum Computing was foremost instituted by Yuri Manin in 1980 and Richard Feynman in 1982. A Quantum Computer with spins as quantum bits was as well devised for employ like a quantum space-time in 1969. There has never been a Quantum Computer Guide like this.

Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved. Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.

In this remarkably illustrative and thoroughly accessible look at one of the most intriguing frontiers in science and computers, award-winning New York Times writer George Johnson reveals the fascinating world of quantum computing—the holy grail of super computers where the computing power of single atoms is harnassed to create machines capable of almost unimaginable calculations in the blink of an eye. As computer chips continue to shrink in size, scientists anticipate the end of the road: A computer in which each switch is comprised of a single atom. Such a device would operate under a different set of physical laws: The laws of quantum mechanics. Johnson gently leads the curious outsider through the surprisingly simple ideas needed to understand this dream, discussing the current state of the revolution, and ultimately assessing the awesome power these machines could have to change our world.

Do you want to learn about cryptography and security in the modern age? THIS BOOK GIVES A DETAILED OVERVIEW OF HISTORY AND DEVELOPMENT OF CRYPTOGRAPHY AND IS FIT EVEN FOR ABSOLUTE BEGINNERS! Cryptography is the practice and study of secure communication. In the old times, cryptography was all about writing messages between that intruders couldn't read or understand. People wrote ciphers and keys and worked hard to decrypt and encrypt important notes. Cryptography was confined mostly to military and diplomatic activities, while regular people didn't have much to do with it in ordinary life. With the development of modern cryptography, we are now surrounded by its codes everywhere. Every message you send over your phone is encrypted. Our banks, schools, and governments rely on secure encryptions. With its prominence in our daily lives, it's a good idea to learn a thing or two about cryptography - not to mention interesting! Here's what you'll find in this book: History of encryption Cyphers from the Classical Era Introduction to modern cryptography Quantum cryptography Hash functions and digital signatures Public key infrastructure AND SO MUCH MORE!
