Quantum language and the migration of scientific concepts
\"This book looks at the use of language in science and in the circulation of scienctific concepts in society at large. More precisely, the book looks at the difficulties physicists faced regarding the use of language while creating quantum mechanics, with the use of quantum concepts in literary criticism and in literature, and with the use of these concepts by the New Age and Post New Age inclined. The principles of quantum physics--and the strange phenomena they describe--originate in and are expressed most precisely with highly abstract algebraic equations. The main challenge posed by quantum phenomena does not lie, however, in its mathematics; it lies instead in how these phenomena strain the limits of comprehension. This book explores the elusive nature of the quantum domain, its problematic relationship to representation in language, and its cultural migration over time\"-- Provided by publisher.

Quirks of the Quantum
Episodic and disconnected, much of postmodern fiction mirrors the world as quantum theorists describe it, according to Samuel Chase Coale. InQuirks of the Quantum,Coale shows how the doubts, misgivings, and ambiguities reflected in the postmodern American novel have been influenced by the metaphors and models of quantum theory. Coale explains the basic facets of quantum theory in lay terms and then applies them to a selection of texts, including Don DeLillo'sUnderworld,Joan Didion'sDemocracy,and Thomas Pynchon'sAgainst the Day.Using a new approach to literature and culture, this book aims to bridge the gap between science and the humanities by suggesting the many areas where they connect.

Shapes of Time in British Twenty-First Century Quantum Fiction
This book addresses the notion of time and temporality and its various conceptualizations in the theories of the new physics, utilized as a thematic and formal framework in the British novel of the twenty-first century. As the Newtonian conception of reality does not provide a reliable framework within which to situate human experience and generate meaning, fiction writers have recognized quantum mechanics as a potent source from which to draw in search of new metaphors. The quantum has become a part of the understanding of reality, and its concepts and assumptions have been absorbed into the textual structure and content of literary fiction. Shapes of Time in British Twenty-First Century Quantum Fiction examines human temporality as mediated by the timeshapes imagined within the context of the new physics, and explores the philosophical implications for human temporality and identity of situating an individual within the realm of physical time. Its chapters deal with various concepts of the new physics connected with temporality, and their appropriation in a selected novel: parallel universes in Andrew Crumey's Sputnik Caledonia (2008), eternal recurrence and Poincaré's theorem in David Mitchell's Cloud Atlas (2004), chaos theory in Samantha Harvey's The Wilderness (2009), and the end of time in Scarlett Thomas's The End of Mr. Y (2006). Each of them corresponds to a different conceptual shape of time: tree, concertina, spiral and snapshot, respectively, which is enacted on the formal level. Analyzing the new time constructs in a narrative, this book thus uncovers passages between scientific and humanistic standpoints, and reveals quantum fiction to be an effective tool for visualizing the subjective non-homogenous experience of private time.

The effective theory of long strings
A
bstract
We present the low-energy effective theory on long strings in quantum field theory, including a streamlined review of previous literature on the subject. Such long strings can appear in the form of solitonic strings, as in the 4d Abelian Higgs model, or in the form of confining strings, as in Yang-Mills theories. The bottom line is that upon expanding in powers of 1
/L
the energy levels of long (closed) strings (where
L
is the length of the string), all the terms up to (and including) order 1
/L
5
are universal. We argue that for excited strings in
D >
3 space-time dimensions there is a universal deviation at order 1
/L
5
from the naive formula that is usually used to fit lattice results. For
D
= 3 this naive formula is valid even at order 1
/L
5
. At order 1
/L

non-universal terms generically appear in all cases. We explain the physical origin of these results, and illuminate them in three different formulations of the effective action of long strings (the relationships among which we partly clarify). In addition, we corroborate these results by an explicit computation of the effective action on long strings in confining theories which have a gravitational dual. These predictions can be tested by precise simulations of 4d Yang-Mills theory on the lattice.

Contemporary Quantum Computing Use Cases: Taxonomy, Review and Challenges
Recently, the popularity of using the expressive power of quantum computing to solve known, challenging problems has increased remarkably. This study aims to develop a clear understanding of the promises and limitations of the current state-of-the-art quantum computing use cases and to define directions for future research in this exciting field. In this regard, we present a literature survey of some of the dedicated work done by researchers in the quantum field. This paper intends to bridge the gap between computer professionals and non-physicists by offering the conceptual and notational information that segregates quantum computing from conventional computing. Subsequently, an attempt has been made to survey existing applications, technological advancements, and contemporary challenges associated with quantum computing.

Leveraging Grover’s Algorithm for Quantum Searchable Encryption in Cloud Infrastructure and its application in AES Resource Estimation
Designing efficient techniques to search over encrypted data space has always been an intriguing security challenge, although many solutions based on classical searching methods have been proposed. Grover’s algorithm, a quantum counterpart of searching algorithms, has proven to provide quadratic speedup over any classical search technique on an unsorted database. However, this algorithm is unable to search over encrypted data space. This study proposed an extension of Grover’s algorithm to enable search over encrypted dataspace, allowing clients with limited-capability quantum resources to delegate complex search operations to an untrusted server. The blindness of data in this protocol is achieved by encrypting qubits using Pauli’s rotation gates that maximally mix the outgoing states. The empirical estimation of the overhead of the computation due to the introduction of this technique has been analyzed. This estimate has been used for comparative analysis, showing the efficiency of the proposed protocol. A practical application of the proposed searchable encryption technique has been utilized to estimate the increase in resources needed to carry out a brute-force attack on AES encryption using secure Grover’s algorithm. Furthermore, an extensive experimental analysis of the effect of noise has been studied using four different noise models: amplitude damping, phase damping, depolarizing noise, and bit-flip noise. The investigation provided useful insight into the behavior of the proposed algorithm under noisy conditions and also estimated the tolerance thresholds of the proposed algorithm under different noise models.

On 1D, N = 4 supersymmetric SYK-type models. Part II
A
bstract
This paper is an extension of our last 1D,
N
= 4 supersymmetric SYK paper [

]. In this paper we introduced the complex linear supermultiplet (CLS), which is “usefully inequivalent” to the chiral supermultiplet. We construct three types of models based on the complex linear supermultiplet containing quartic interactions from modified CLS kinetic term, quartic interactions from 3-pt vertices integrated over the whole superspace, and 2(
q −
1)-pt interactions generated via superpotentials respectively. A strong evidence for the inevitability of dynamical bosons for 1D,
N
= 4 SYK is also presented.

A review on quantum computing and deep learning algorithms and their applications
In this paper, we describe a review concerning the Quantum Computing (QC) and Deep Learning (DL) areas and their applications in Computational Intelligence (CI). Quantum algorithms (QAs), engage the rules of quantum mechanics to solve problems using quantum information, where the quantum information is concerning the state of a quantum system, which can be manipulated using quantum information algorithms and other processing techniques. Nowadays, many QAs have been proposed, whose general conclusion is that using the effects of quantum mechanics results in a significant speedup (exponential, polynomial, super polynomial) over the traditional algorithms. This implies that some complex problems currently intractable with traditional algorithms can be solved with QA. On the other hand, DL algorithms offer what is known as machine learning techniques. DL is concerned with teaching a computer to filter inputs through layers to learn how to predict and classify information. Observations can be in the form of plain text, images, or sound. The inspiration for deep learning is the way that the human brain filters information. Therefore, in this research, we analyzed these two areas to observe the most relevant works and applications developed by the researchers in the world.
