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.

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" and its radical disruption of the meaning/matter dualism at the heart of the dominant Western tradition. In doing so, the essays in this collection variously approach rhetoric as a "figure of entanglement" that enables a rethinking of meaning as itself performative, material, and ecological. Contributors thereby 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 "prehistoric" emergence of human consciousness. With a new foreword by the editors and afterword by Laurie E.

"The aim of this thesis is to study the quantum entanglement and, in particular, under which circumstances is maximum.In the first place, Bell's inequalities are analyzed from an operational point of view. In particular, we focus on those involving qutrits. The states that maximally violate these inequalities are of the GHZ type, for inequalities involving qubits, and little deformations of GHZ state, for those involving qutrits. This result shows that, although maximum entanglement and non-locality are very close concepts, they are not equivalent.In the second place, multipartite entanglement in spin chains is studied. We use as a figure of merit the hyperdeterminant and two polynomial invariants, S and T. These figures quantify a specific type of quadripartite entanglement, as demonstrated by an analysis of well-known quantum states such as the GHZ or W. In an Ising spin chain, we observe a pronounced peak near the quantum phase transition. Similar results are observed for the XXZ and Haldane- Shastry models for the case of the S and T invariants. For that reason, we conclude that these figures of merit are sensitive to quantum phase transitions.The second part of the thesis focuses on the field of quantum computing. This field has experienced a significant expansion in recent years. Due to this growth, several companies have started to develop prototypes of quantum computers. For this reason, one line of research in quantum computing is to propose methods to benchmark these machines.One of the methods presented in this thesis consists of the exact simulation of a XY spin chain. We propose a circuit that diagonalizes the XY Hamiltonian, which allows simulating time evolution and thermal states as well. Since this model is exactly solvable, the results obtained from a quantum computer can be compared with the theoretical solution. After running this circuit for four qubits on two IBM computers and one from Rigetti computing company, we obtain worse results than expected. With this, we conclude that there are error sources that, in general, are not being taken into account and that become relevant even in such small circuits.Moreover, we propose another method to test quantum computers performance: the simulation of absolutely maximally entangled states. The implementation of these circuits is a hard but necessary test for a quantum computer since the advantage of quantum algorithms lies in the generation of entanglement.Finally, we study the generation of entanglement at the most fundamental level: particle physics. We obtain that the QED interaction at tree-level is dictated by the imposition of maximal entanglement in outgoing particles. We apply the same philosophy in processes involving weak neutral currents obtaining that the weak mixing angle must be pi / 6, very close to the experimental value." -- TDX.

By foregrounding the ways that human existence is bound together with the lives of other entities, contemporary cultural theorists have sought to move beyond an anthropocentric worldview. Yet as Eva Haifa Giraud contends in What Comes after Entanglement?, for all their conceptual power in implicating humans in ecologically damaging practices, these theories can undermine scope for political action. Drawing inspiration from activist projects between the 1980s and the present that range from anticapitalist media experiments and vegan food activism to social media campaigns against animal research, Giraud explores possibilities for action while fleshing out the tensions between theory and practice. Rather than an activist ethics based solely on relationality and entanglement, Giraud calls for what she describes as an ethics of exclusion, which would attend to the entities, practices, and ways of being that are foreclosed when other entangled realities are realized. Such an ethics of exclusion emphasizes foreclosures in the context of human entanglement in order to foster the conditions for people to create meaningful political change.

This original book is a much needed and far reaching exploration of post-apartheid South African life worlds. Entanglement aims to capture the contradictory mixture of innovation and inertia, of loss, violence and xenophobia as well as experimentation and desegregation, which characterises the present. The author explores the concept of entanglement in relation to readings of literature, new media forms and painting. In the process, she moves away from a persistent apartheid optic, drawing on ideas of sameness and difference, and their limits, in order to elicit ways of living and imagining that are just starting to take shape and for which we might not yet have a name. In the background of her investigations lies a preoccupation with a future-oriented politics, one that builds on largely unexplored terrains of mutuality while being attentive to a historical experience of confrontation and injury.

Quantum Entanglement

Quantum Entanglement

An exploration of quantum entanglement and the ways in which it contradicts our everyday 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.

This book provides an interdisciplinary perspective on one of the most fascinating and important open questions in science: What is quantum mechanics talking about? Quantum theory is perhaps our best confirmed physical theory. However, despite its great empirical effectiveness and the subsequent technological developments that it gave rise to in the 20th century, from the interpretation of the periodic table of elements to CD players, holograms and quantum state teleportation, it stands even today without a universally accepted interpretation. The novelty of the book comes from the multiple viewpoints and subjects investigated by a group of researchers from Europe and North and South America.

Unique in that it is jointly written by an experimentalist and a theorist, this monograph presents universal quantum computation based on quantum teleportation as an elementary subroutine and multi-party entanglement as a universal resource. Optical approaches to measurement-based quantum computation are also described, including schemes for quantum error correction, with most of the experiments carried out by the authors themselves. Ranging from the theoretical background to the details of the experimental realization, the book describes results and advances in the field, backed by numerous illustrations of the authors' experimental setups. Aimed at researchers, physicists, and graduate and PhD students in physics, theoretical quantum optics, quantum mechanics, and quantum information.

In 2180, travel to neighbouring star systems has been mastered thanks to quantum teleportation using the 'entanglement' of sub-atomic matter; astronauts on earth can be duplicated on a remote world once the dupliport chamber has arrived there. In this way a variety of worlds can be explored, but what humanity discovers is both surprising and disturbing, enlightening and shocking. Each alternative to mankind that the astronauts find, sheds light on human shortcomings and potential while offering fresh perspectives of life on Earth. Meanwhile, at home, the lives of the astronauts and those in charge of the missions will never be the same again.

Quantum information theory is a branch of science at the frontier of physics, mathematics, and information science, and offers a variety of solutions that are impossible using classical theory. This book provides a detailed introduction to the key concepts used in processing quantum information and reveals that quantum mechanics is a generalisation of classical probability theory. The second edition contains new sections and entirely new chapters: the hot topic of multipartite entanglement; in-depth discussion of the discrete structures in finite dimensional Hilbert space, including unitary operator bases, mutually unbiased bases, symmetric informationally complete generalized measurements, discrete Wigner function, and unitary designs; the Gleason and Kochen-Specker theorems; the proof of the Lieb conjecture; the measure concentration phenomenon; and the Hastings' non-additivity theorem. This richly-illustrated book will be useful to a broad audience of graduates and researchers interested in quantum information theory. Exercises follow each chapter, with hints and answers supplied.

Entanglement theory posits that the interrelationship of humans and objects is a delimiting characteristic of human history and culture. This edited volume of original studies by leading archaeological theorists applies this concept to a broad range of topics, including archaeological science, heritage, and theory itself. In the theoretical explications and ten case studies, the editors and contributing authors: -build on the intersections between science, humanities and ecology to provide a more fine-grained, multi-scalar treatment emanating from the long-term perspective that characterizes archaeological research; -bring to light the subtle and unacknowledged paths that configure historical circumstances and bind human intentionality; -examine the constructions of personhood, the rigidity of path dependencies, the unpredictable connections between humans and objects and the intricate paths of past events in varied geographic and historical contexts that channel future actions. This broad focus is inclusive of early complex developments in Asia and Europe, imperial and state strategies in the Andes and Mesoamerica, continuities of postcolonialism in North America, and the unforeseen and complex consequences that derive from archaeological practices. This volume will appeal to archaeologists and their advanced students.

As demand for on-chip functionalities and requirements for low power operation continue to increase as a result of the emergence in mobile, wearable and internet-of-things (IoT) products, 3D/2.5D have been identified as an inevitable path moving forward. As circuits become more and more complex, especially three-dimensional ones, new insights have to be developed in many domains, including electrical, thermal, noise, interconnects, and parasites. It is the entanglement of such domains that begins the very key challenge as we enter in 3D nano-electronics. This book aims to develop this new paradigm, going to a synthesis beginning between many technical aspects.
