Superconducting Quantum Devices: SQUIDs, QuBits, and Quantum-Limited Amplifiers

This lecture provides a comprehensive introduction to the physics and applications of superconducting quantum devices (SDR). In particular, we cover the physics of Josephson tunnel junctions, which are of similar importance to SQDs as transistors are to modern semiconductor circuits. We cover superconducting quantum interference devices (SQUIDs), which are currently the most sensitive broadband devices for measuring various physical quantities such as voltage, current, or magnetic field that can be naturally converted to magnetic flux. We discuss different types of superconducting qubits and provide an introduction to SQD-based quantum-limited amplifiers, which are currently the only devices that overcome the existing noise limitations of conventional semiconductor electronics.
