Photons are an attractive option for testing fundamental quantum physics and developing new quantum-enhanced technology, including highly advanced computers and simulators, as well as precision sensing beyond shot-noise. Traditionally, bulk optical components have been bolted onto optical benches to realize metre-scale quantum circuits. However this approach is ultimately proving unwieldy for increasing the complexity and for scaling up to practical quantum technologies based on photons. The work presented here demonstrates a series of quantum photonic devices based on waveguide circuits embedded in miniature monolithic chips. This represents a paradigm shift in the underlying architecture of quantum optics and provides key building blocks for all-optical and hybrid quantum technologies.
The race is on to construct the first quantum code breaker, as the winner will hold the key to the entire Internet. From international, multibillion-dollar financial transactions to top-secret government communications, all would be vulnerable to the secret-code-breaking ability of the quantum computer. Written by a renowned quantum physicist closely involved in the U.S. government’s development of quantum information science, Schrödinger’s Killer App: Race to Build the World’s First Quantum Computer presents an inside look at the government’s quest to build a quantum computer capable of solving complex mathematical problems and hacking the public-key encryption codes used to secure the Internet. The "killer application" refers to Shor’s quantum factoring algorithm, which would unveil the encrypted communications of the entire Internet if a quantum computer could be built to run the algorithm. Schrödinger’s notion of quantum entanglement—and his infamous cat—is at the heart of it all. The book develops the concept of entanglement in the historical context of Einstein’s 30-year battle with the physics community over the true meaning of quantum theory. It discusses the remedy to the threat posed by the quantum code breaker: quantum cryptography, which is unbreakable even by the quantum computer. The author also covers applications to other important areas, such as quantum physics simulators, synchronized clocks, quantum search engines, quantum sensors, and imaging devices. In addition, he takes readers on a philosophical journey that considers the future ramifications of quantum technologies. Interspersed with amusing and personal anecdotes, this book presents quantum computing and the closely connected foundations of quantum mechanics in an engaging manner accessible to non-specialists. Requiring no formal training in physics or advanced mathematics, it explains difficult topics, including quantum entanglement, Schrödinger’s cat, Bell’s inequality, and quantum computational complexity, using simple analogies.
Always the serious student's choice for a Trusts Law textbook, the new seventh edition of Moffat's Trusts Law once again provides a clear examination of the rules of Trusts, retaining its hallmark combination of a contextualised approach and a commercial focus. The impact of statutory developments and a wealth of new cases – including the Supreme Court and Privy Council decisions in Patel v. Mirza [2016] UKSC 42, PJS v. News Group Newspapers Ltd [2016] UKSC, Burnden Holdings v. Fielding [2018] UKSC 14, and Federal Republic of Brazil v. Durant [2015] UKPC 35 – are explored. A streamlining of the chapters on charitable Trusts, better to align the book with the typical Trusts Law course, helps students understand the new directions being taken in the areas of Trust Law and equitable remedies.
Mammals of Africa (MoA) is a series of six volumes which describes, in detail, every currently recognized species of African land mammal. This is the first time that such extensive coverage has ever been attempted, and the volumes incorporate the very latest information and detailed discussion of the morphology, distribution, biology and evolution (including reference to fossil and molecular data) of Africa's mammals. With 1,160 species and 16 orders, Africa has the greatest diversity and abundance of mammals in the world. The reasons for this and the mechanisms behind their evolution are given special attention in the series. Each volume follows the same format, with detailed profiles of every species and higher taxa. The series includes some 660 colour illustrations by Jonathan Kingdon and his many drawings highlight details of morphology and behaviour of the species concerned. Diagrams, schematic details and line drawings of skulls and jaws are by Jonathan Kingdon and Meredith Happold. Every species also includes a detailed distribution map. Extensive references alert readers to more detailed information. Volume I: Introductory Chapters and Afrotheria (352 pages) Volume II: Primates (560 pages) Volume III: Rodents, Hares and Rabbits (784 pages) Volume IV: Hedgehogs, Shrews and Bats (800 pages) Volume V: Carnivores, Pangolins, Equids and Rhinoceroses (560 pages) Volume VI: Pigs, Hippopotamuses, Chevrotain, Giraffes, Deer and Bovids (704 pages)
This one-of-a-kind guide offers easy-to-understand explanations, advice, and management options for patients or parents of patients with cystic fibrosis. The book explains the disease process, outlines the fundamentals of diagnosing and screening, and addresses the challenges of treatment for those living with CF. As one reviewer said, this book “is the only complete answer book for everyone living with the disease. It is an indispensable resource for families of children with CF, adolescent and adult patients, and physicians, nurses, respiratory therapists, and social workers involved in the care of CF patients.”
From Dust They Came tells the story of Dust Bowl refugees' experiences in the camps that New Deal reformers built throughout agricultural California to redeem migratory farm workers from lives of vulnerability and filth, and from pre-modern ways of living and believing"--
A much-overlooked aspect of the Gospel of Matthew is the theme of heaven and earth. Rather than being a reverential circumlocution for God, 'heaven' in Matthew is part of a highly developed discourse of heaven and earth language. Matthew's idiolectic way of using heaven language consists of four aspects: 1) a distinction in meaning between singular and plural forms of "ouranos"; 2) frequent use of the heaven and earth word pair; 3) regular reference to the Father in heaven; and 4) the recurrent use of the Matthean expression, kingdom of heaven. This book examines the historical precedents for each of these aspects and shows in Matthew how they serve one overriding theological purpose: to highlight the tension that currently exists between heaven and earth or God and humanity, while looking forward to its eschatological resolution.
