Quantum Computing

The ultimate non-technical guide to the fast-developing world of quantum computing Computer technology has improved exponentially over the last 50 years. But the headroom for bigger and better electronic solutions is running out. Our best hope is to engage the power of quantum physics. 'Quantum algorithms' had already been written long before hardware was built. These would enable, for example, a quantum computer to exponentially speed up an information search, or to crack the mathematical trick behind internet security. However, making a quantum computer is incredibly difficult. Despite hundreds of laboratories around the world working on them, we are only just seeing them come close to 'supremacy' where they can outperform a traditional computer. In this approachable introduction, Brian Clegg explains algorithms and their quantum counterparts, explores the physical building blocks and quantum weirdness necessary to make a quantum computer, and uncovers the capabilities of the current generation of machines.

A friendly introduction to quantum programming. What if you had a computer that could process billions of different inputs at the same time? Quantum computing is a radically new way to think about algorithms and data. It can feel mysterious or technically challenging, but it doesn't have to be. If you want to understand how quantum computers work--and how to program them--this friendly, self-contained guide is for you. This approachable yet rigorous book walks you step-by-step through quantum computing fundamentals, such as superposition, quantum gates, interference, entanglement, and measurement, then teaches you how to write real quantum programs. Along the way, you'll: Understand how to store and transform quantum information Grasp the surprising process of quantum measurement Explore Simon's, Grover's, and Shor's algorithms Write and run your own quantum code using free simulators and live hardware Author Andrew Glassner is known for turning complex topics into accessible and enjoyable learning experiences. In this book, he brings visual thinking, clarity, context, and precision to the strange and fascinating world of quantum programming. All the ideas and math are built up slowly so you'll master every step. Whether you're a programmer, student, educator, scientist, poet, or anyone else who loves new ideas that stretch your mind, this is the guide that will take you from "What is a qubit?" to writing and running working quantum algorithms with curiosity, creativity, and confidence.

QUANTUM COMPUTING A helpful introduction to all aspects of quantum computing Quantum computing is a field combining quantum mechanics—the physical science of nature at the scale of atoms and subatomic particles—and information science. Where ordinary computing uses bits, logical values whose position can either be 0 or 1, quantum computing is built around qubits, a fundamental unit of quantum information which can exist in a superposition of both states. As quantum computers are able to complete certain kinds of functions more accurately and efficiently than computers built on classical binary logic, quantum computing is an emerging frontier which promises to revolutionize information science and its applications. This book provides a concise, accessible introduction to quantum computing. It begins by introducing the essentials of quantum mechanics that information and computer scientists require, before moving to detailed discussions of quantum computing in theory and practice. As quantum computing becomes an ever-greater part of the global information technology landscape, the knowledge in Quantum Computing will position readers to join a vital and highly marketable field of research and development. The book’s readers will also find: Detailed diagrams and illustrations throughout A broadly applicable quantum algorithm that improves on the best-known classical algorithms for a wide range of problems In-depth discussion of essential topics including key distribution, cluster state quantum computing, superconducting qubits, and more Quantum Computing is perfect for advanced undergraduate and graduate students in computer science, engineering, mathematics, or the physical sciences, as well as for researchers and academics at the intersection of these fields who want a concise reference.
