Figures of Entanglement


Book Description

Recent and ongoing "new materialisms" scholarship seeks to fundamentally reshape the humanities and their relationship with the sciences. While this work comprises multiple and varied currents, one of the most important, yet whose distinctive merits are arguably often underappreciated, is that influenced by the theoretical physicist and feminist philosopher Karen Barad. The first volume devoted to bringing Barad’s work into conversation with the disciplines of rhetoric and communication studies, this collection organizes that conversation primarily around her notion of "entanglement", which encourages an understanding of meaning as inherently performative, material, and ecological. In doing so, the essays in this collection variously approach rhetoric as a "figure of entanglement" in ways that contribute to and enrich both rhetoric and Barad’s theorizing. Topics range from politics to breast cancer, genealogy, the trope of academic "turns," Marx’s notion of exchange, and the "prehistoric" emergence of human consciousness. With a new foreword by the editors and afterword by Laurie E. Gries, this collection is otherwise reprinted from the 2016 "Figures of Entanglement" special issue of the journal Review of Communication.




Figures of Entanglement


Book Description

The essays in this book broaden and enrich the scope, at once, of both rhetoric and Barad's theorizing through entangled reworkings of topics ranging from politics to breast cancer, genealogy, the trope of academic turns, Marx's notion of exchange, and the emergence of human consciousness.




Holographic Entanglement Entropy


Book Description

This book provides a comprehensive overview of developments in the field of holographic entanglement entropy. Within the context of the AdS/CFT correspondence, it is shown how quantum entanglement is computed by the area of certain extremal surfaces. The general lessons one can learn from this connection are drawn out for quantum field theories, many-body physics, and quantum gravity. An overview of the necessary background material is provided together with a flavor of the exciting open questions that are currently being discussed. The book is divided into four main parts. In the first part, the concept of entanglement, and methods for computing it, in quantum field theories is reviewed. In the second part, an overview of the AdS/CFT correspondence is given and the holographic entanglement entropy prescription is explained. In the third part, the time-dependence of entanglement entropy in out-of-equilibrium systems, and applications to many body physics are explored using holographic methods. The last part focuses on the connection between entanglement and geometry. Known constraints on the holographic map, as well as, elaboration of entanglement being a fundamental building block of geometry are explained. The book is a useful resource for researchers and graduate students interested in string theory and holography, condensed matter and quantum information, as it tries to connect these different subjects linked by the common theme of quantum entanglement.

Quantum Aspects of Life


Book Description

This book presents the hotly debated question of whether quantum mechanics plays a non-trivial role in biology. In a timely way, it sets out a distinct quantum biology agenda. The burgeoning fields of nanotechnology, biotechnology, quantum technology, and quantum information processing are now strongly converging. The acronym BINS, for Bio-Info-Nano-Systems, has been coined to describe the synergetic interface of these several disciplines. The living cell is an information replicating and processing system that is replete with naturally-evolved nanomachines, which at some level require a quantum mechanical description. As quantum engineering and nanotechnology meet, increasing use will be made of biological structures, or hybrids of biological and fabricated systems, for producing novel devices for information storage and processing and other tasks. An understanding of these systems at a quantum mechanical level will be indispensable.




Quantum Computing for the Quantum Curious


Book Description

This open access book makes quantum computing more accessible than ever before. A fast-growing field at the intersection of physics and computer science, quantum computing promises to have revolutionary capabilities far surpassing “classical” computation. Getting a grip on the science behind the hype can be tough: at its heart lies quantum mechanics, whose enigmatic concepts can be imposing for the novice. This classroom-tested textbook uses simple language, minimal math, and plenty of examples to explain the three key principles behind quantum computers: superposition, quantum measurement, and entanglement. It then goes on to explain how this quantum world opens up a whole new paradigm of computing. The book bridges the gap between popular science articles and advanced textbooks by making key ideas accessible with just high school physics as a prerequisite. Each unit is broken down into sections labelled by difficulty level, allowing the course to be tailored to the student’s experience of math and abstract reasoning. Problem sets and simulation-based labs of various levels reinforce the concepts described in the text and give the reader hands-on experience running quantum programs. This book can thus be used at the high school level after the AP or IB exams, in an extracurricular club, or as an independent project resource to give students a taste of what quantum computing is really about. At the college level, it can be used as a supplementary text to enhance a variety of courses in science and computing, or as a self-study guide for students who want to get ahead. Additionally, readers in business, finance, or industry will find it a quick and useful primer on the science behind computing’s future.




Quantum Entanglement


Book Description

A concise, non-technical exploration of quantum entanglement—the enigma Albert Einstein called ‘spooky action at a distance’—and how it contradicts our assumptions about the ultimate nature of reality. Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can’t affect the other. Quantum entanglement—called by Einstein “spooky action at a distance”—rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying? In this volume in the MIT Press Essential Knowledge series, Jed Brody equips readers to decide for themselves. He explains how our commonsense assumptions impose constraints—from which entangled particles break free. Brody explores such concepts as local realism, Bell’s inequality, polarization, time dilation, and special relativity. He introduces readers to imaginary physicists Alice and Bob and their photon analyses; points out that it's easier to reject falsehood than establish the truth; and reports that some physicists explain entanglement by arguing that we live in a cross-section of a higher-dimensional reality. He examines a variety of viewpoints held by physicists, including quantum decoherence, Niels Bohr's Copenhagen interpretation, genuine fortuitousness, and QBism. This relatively recent interpretation, an abbreviation of “quantum Bayesianism,” holds that there's no such thing as an absolutely accurate, objective probability “out there,” that quantum mechanical probabilities are subjective judgments, and there's no “action at a distance,” spooky or otherwise.




Entangled Worlds


Book Description

Historically speaking, theology can be said to operate “materiaphobically.” Protestant Christianity in particular has bestowed upon theology a privilege of the soul over the body and belief over practice, in line with the distinction between a disembodied God and the inanimate world “He” created. Like all other human, social, and natural sciences, religious studies imported these theological dualisms into a purportedly secular modernity, mapping them furthermore onto the distinction between a rational, “enlightened” Europe on the one hand and a variously emotional, “primitive,” and “animist” non-Europe on the other. The “new materialisms” currently coursing through cultural, feminist, political, and queer theories seek to displace human privilege by attending to the agency of matter itself. Far from being passive or inert, they show us that matter acts, creates, destroys, and transforms—and, as such, is more of a process than a thing. Entangled Worlds examines the intersections of religion and new and old materialisms. Calling upon an interdisciplinary throng of scholars in science studies, religious studies, and theology, it assembles a multiplicity of experimental perspectives on materiality: What is matter, how does it materialize, and what sorts of worlds are enacted in its varied entanglements with divinity? While both theology and religious studies have over the past few decades come to prioritize the material contexts and bodily ecologies of more-than-human life, Entangled Worlds sets forth the first multivocal conversation between religious studies, theology, and the body of “the new materialism.” Here disciplines and traditions touch, transgress, and contaminate one another across their several carefully specified contexts. And in the responsiveness of this mutual touching of science, religion, philosophy, and theology, the growing complexity of our entanglements takes on a consistent ethical texture of urgency.
