Book Description
Quantum science and technology provides new possibilities in processing information, simulating novel materials, and answering fundamental questions beyond the reach of classical methods. Realizing these goals relies on the advancement of physical platforms, among which superconducting circuits have been one of the leading candidates offering complete control and read-out over individual qubits and the potential to scale up. However, most circuit-based multi-qubit architectures only include nearest-neighbor (NN) coupling between qubits, which limits the efficient implementation of low-overhead quantum error correction and access to a wide range of physical models using analog quantum simulation

Book Description
Superconducting quantum circuits are among the most promising solutions for the development of scalable quantum computers. Built with sizes that range from microns to tens of metres using superconducting fabrication techniques and microwave technology, superconducting circuits demonstrate distinctive quantum properties such as superposition and entanglement at cryogenic temperatures. This book provides a comprehensive and self-contained introduction to the world of superconducting quantum circuits, and how they are used in current quantum technology. Beginning with a description of their basic superconducting properties, the author then explores their use in quantum systems, showing how they can emulate individual photons and atoms, and ultimately behave as qubits within highly connected quantum systems. Particular attention is paid to cutting-edge applications of these superconducting circuits in quantum computing and quantum simulation. Written for graduate students and junior researchers, this accessible text includes numerous homework problems and worked examples.

Book Description
Explore the intersection of computer science, physics, and electrical and computer engineering with this discussion of the engineering of quantum computers In Principles of Superconducting Quantum Computers, a pair of distinguished researchers delivers a comprehensive and insightful discussion of the building of quantum computing hardware and systems. Bridging the gaps between computer science, physics, and electrical and computer engineering, the book focuses on the engineering topics of devices, circuits, control, and error correction. Using data from actual quantum computers, the authors illustrate critical concepts from quantum computing. Questions and problems at the end of each chapter assist students with learning and retention, while the text offers descriptions of fundamentals concepts ranging from the physics of gates to quantum error correction techniques. The authors provide efficient implementations of classical computations, and the book comes complete with a solutions manual and demonstrations of many of the concepts discussed within. It also includes: A thorough introduction to qubits, gates, and circuits, including unitary transformations, single qubit gates, and controlled (two qubit) gates Comprehensive explorations of the physics of single qubit gates, including the requirements for a quantum computer, rotations, two-state systems, and Rabi oscillations Practical discussions of the physics of two qubit gates, including tunable qubits, SWAP gates, controlled-NOT gates, and fixed frequency qubits In-depth examinations of superconducting quantum computer systems, including the need for cryogenic temperatures, transmission lines, S parameters, and more Ideal for senior-level undergraduate and graduate students in electrical and computer engineering programs, Principles of Superconducting Quantum Computers also deserves a place in the libraries of practicing engineers seeking a better understanding of quantum computer systems.

Book Description
This work describes theoretical and experimental advances towards the realization of a hybrid quantum processor in which the collective degrees of freedom of an ensemble of spins in a crystal are used as a multi-qubit register for superconducting qubits. A memory protocol made of write, read and reset operations is first presented, followed by the demonstration of building blocks of its implementation with NV center spins in diamond. Qubit states are written by resonant absorption of a microwave photon in the spin ensemble and read out of the memory on-demand by applying Hahn echo refocusing techniques to the spins. The reset step is implemented in between two successive write-read sequences using optical repumping of the spins.

Book Description
Intense recent activity in the field of high-temperature superconductivity both in Japan and in the rest of the world was discussed at the First International Symposium on Superconductivity held in Nagoya in August 1988. Current research and development efforts by major Japanese companies in the field of high-temperature superconductivity are reported by leading company scientists, to give an overview of the high level of activity in the area. Progress in the development of new materials and recent theoretical work is reported both from Japanese and international researchers. Contributions are organized by topic, with such topics as crystal chemistry and electronic structure, processing and microstructure, tapes and thick films, wires and coils, and thin film processing and properties. Future applications of superconductivity including magnetic levitation vehicles, electronics based on Josephson junctions, power delivery, energy storage, ship propulsion and magnetic resonance imaging are particularly stressed.

Book Description
Superconductivity made accessible-a unique introduction. Does superconductivity have to be hard to understand? No, says Alan Kadin, as he proceeds to make the field accessible to engineers, applied physicists, even undergraduate students in electrical engineering. Setting advanced theories aside, Dr. Kadin uses simple circuit models to develop an understanding of the physics of superconductors, then applies this knowledge to superconducting circuits and systems. He covers cutting-edge circuit applications and materials along with practical examples-giving readers insight into the pros and cons of various superconductors and what superconductivity has to offer for different disciplines. End-of-chapter problems as well as numerous conceptual line drawings, circuit schematics, and plots complement the following topics: * The central role of inductance and kinetic inductance. * Transmission line model for RF and dc properties. * Dual circuit transformations to follow vortex and fluxon motion. * A balanced coverage of low-temperature and high-temperature superconductors. * Both large-scale (power) and small-scale (electronic) applications. * Applications of superconducting devices to electromagnetic radiation detectors. * The use of SPICE to simulate Josephson junctions and circuits. *An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department.

Book Description
In this work, I first construct a unified simulation platform, where superconducting electronics can be designed and optimized with high performance and accuracy. For this purpose, I first select numerical simulation methods that can deal with the highly non-linear characteristics of the superconducting devices. I validate the simulated responses with experimental data on device and circuit level examples. Following the implementation of the simulator, I use this framework to analyze existing superconducting nanowire based technologies, and optimize them for wider operation regimes and higher performance metrics. I use nanofabrication processes to realize these devices and conduct liquid helium immersion measurements to characterize them experimentally. Optimized devices show superior characteristics that demonstrate the predictive capabilities of this simulator. Finally, I use this simulator to design a superconducting nanowire based deep neural network training accelerator. I design, implement, and characterize a unit cell for this application. These local processors have significant device-level advantages over the readily available non-volatile memory technologies in realizing mixed-signal architectures. The devices produced throughout this work have immediate and near-term applications, proving the merit of having a high-performance simulator.
