High-temperature superconducting nano quantum interference devices and magnetometer

Description

Our intent is to offer the reader an in-depth, systematic treatment of high-temperature superconducting material (HTS), superconducting quantum interference devices (SQUIDs) and their many applications. The book is organized into five chapters, the first being devoted to the applications of superconductors from macroscopic to microscopic, ranging from superconducting bulk, superconducting film, superconducting nanowire to Josephson junction. In second chapter, the present work attempts to review the various known types of weak links including the nano-wire, bi-epitaxial, bi-crystal, step-edge, and beam irradiation-based high-Tc Junctions. Chapter 3 is concerned with the basic theory and fabrication process for high-Tc YBCO nanoSQUID. Meanwhile, the issue of device degradation and 1/f noise are discussed. Subsequently, in Chapter 4, we review the development of two different types of YBCO magnetometers and high-Tc SQUID gradiometers. In conclusion, with the rapid development of quantum sensing, quantum communication and quantum computing, the Josephson junctions, the core elements of superconducting quantum circuits, are expected to more profound impact on our lives.
