Book Description
This book concerns a Josephson device for supercomputers which has extremely low heat dissipation (about 106 times less than semiconductor devices and 103 times less than voltage-based Josephson devices). In the previous book on Quantum Flux Parametrons (QFPs), DC Flux Parametron, the basic device operation are described. This book deals in much greater depth on the problems which are faced by the QFP. The device characteristics are worked out in detail showing clearly the analysis methods used. A new logic gate using the QFP is described with respect to its basic scheme, operation, and ways for forming logic circuits. The problems faced by the basic QFP are much reduced in the new logic gate. As the QFP operates near the Heisenberg and Boltzmann limits for computing devices, we also show the relationship between speed and stability. The book contains the latest analytical results on QFPs.The material presented in the book can be understood with very little mathematical training or knowledge about superconducting physics. It is also self-contained and does not require reading of other material. Most of the device characteristics can be reproduced from the equations given using simple programs. A circuit simulator is not needed except for high speeds when transient behavior becomes important.

DC Flux Parametron

ISBN: 9789971501136
Category : Technology & Engineering
Languages : en
Pages : 214
Book Description
The direct current flux parametron using Josephson junction and based on the principle of parametron seems to be the answer for the search of new technology for the future needs of computer power. The combination of its very high switching speed and highly integrable Josephson junction with the established parametron computer technology accounts for its high performance. This book presents the new type of Josephson computer technology which is fundamentally different from the conventional approach. In this approach, a logic state is represented by a flux polarity whereas the conventional approach uses a voltage state to represent a logic state.

The SQUID Handbook
Author: John Clarke
Publisher: John Wiley & Sons
ISBN: 3527604588
Category : Science
Languages : en
Pages : 409
Book Description
This two-volume handbook offers a comprehensive and well coordinated presentation of SQUIDs (Superconducting Quantum Interference Devices), including device fundamentals, design, technology, system construction and multiple applications. It is intended to bridge the gap between fundamentals and applications, and will be a valuable textbook reference for graduate students and for professionals engaged in SQUID research and engineering. It will also be of use to specialists in multiple fields of practical SQUID applications, from human brain research and heart diagnostics to airplane and nuclear plant testing to prospecting for oil, minerals and buried ordnance. The first volume contains chapters presenting the theory of SQUIDs, their fabrication from low- and high-temperature superconductors, the necessary readout electronics, and the design and performance of practical direct current (dc) and radio-frequency (rf) SQUIDs. This volume concludes with an overview of the most important SQUID system issues. An appendix summarizes briefly the foundations of superconductivity that are necessary to understand SQUIDs. A glossary and tables of units and constants are also included. The second volume of the handbook will deal with applications of SQUIDs and SQUID systems.

Publisher: World Scientific
ISBN: 9789810234232
Category : Technology & Engineering
Languages : en
Pages : 202
Book Description
Obstacle Avoidance in Multi-robot Systems: Experiments in Parallel Genetic Algorithms offers a novel framework for solving the path planning problem for robot manipulators. Simple and efficient solutions are proposed for the path planning problem based on genetic algorithms. One of the attractive features of genetic algorithms is their ability to solve formidable problems in a robust and straightforward manner. Moreover, genetic algorithms are inherently parallel in nature, which makes them ideal candidates for parallel computing implementations.By combining the robustness of genetic algorithms with the power of parallel computers, this book provides an effective and practical approach to solving path planning problems. The book gives details of implementations that allow a better understanding of the complexities involved in the development of parallel path planning algorithms. The material presented is interdisciplinary in nature ? it combines topics from robotics, genetic algorithms, and parallel processing. The book can be used by practitioners and researchers in computer science and engineering.

Book Description
Quantum Flux Parametron(QFP) is a Josephson junction device which uses the polarities of a unit of quantum flux to represent a bit of binary information. The low power consumption and the inductive nature of signal transfer of QFP promise the realizability of a highly integrated Josephson Supercomputer. The miniaturization and the inductively connected circuits pose new challenges and problems to the designers of such a computer system. This volume contains five papers which provide detailed illustrations of the essential problems in the design of Josephson Supercomputers.The problems include (i) the three-dimensional packaging problems in the highly integrated system, (ii) the detection of trapped magnetic quanta, (iii) the computation of three-dimensional inductance and (iv) the elimination or alleviation of various internal and external operational problems of QFP arising from the limitation of the current fabrication technology as well as the inherent problems of direct coupling of QFP

Fundamentals and Frontiers of the Josephson Effect
Author: Francesco Tafuri
Publisher: Springer Nature
ISBN: 3030207269
Category : Technology & Engineering
Languages : en
Pages : 884
Book Description
This book provides a comprehensive and up-to-date description of the Josephson effect, a topic of never-ending interest in both fundamental and applied physics. In this volume, world-renowned experts present the unique aspects of the physics of the Josephson effect, resulting from the use of new materials, of hybrid architectures and from the possibility of realizing nanoscale junctions. These new experimental capabilities lead to systems where novel coherent phenomena and transport processes emerge. All this is of great relevance and impact, especially when combined with the didactic approach of the book. The reader will benefit from a general and modern view of coherent phenomena in weakly-coupled superconductors on a macroscopic scale. Topics that have been only recently discussed in specialized papers and in short reviews are described here for the first time and organized in a general framework. An important section of the book is also devoted to applications, with focus on long-term, future applications. In addition to a significant number of illustrations, the book includes numerous tables for comparative studies on technical aspects.

Publisher: Springer Nature
ISBN: 3030768856
Category : Technology & Engineering
Languages : en
Pages : 252
Book Description
High efficiency, large scale, stationary computing systems – supercomputers and data centers – are becoming increasingly important due to the movement of data storage and processing onto remote cloud servers. This book is dedicated to a technology particularly appropriate for this application – superconductive electronics, in particular, rapid single flux quantum circuits. The primary purpose of this book is to introduce and systematize recent developments in superconductive electronics into a cohesive whole to support the further development of large scale computing systems. A brief background into the physics of superconductivity and the operation of common superconductive devices is provided, followed by an introduction into different superconductive logic families, including the logic gates, interconnect, and bias current distribution. Synchronization, fabrication, and electronic design automation methodologies are presented, reviewing both widely established concepts and techniques as well as recent approaches. Issues related to memory, synchronization, bias networks, and testability are described, and models, circuits, algorithms, and design methodologies are discussed and placed in context. The aim of this book is to provide insight and engineering intuition into the design of large scale digital superconductive circuits and systems.
