Quantum Metrology: Superconducting Devices and Qubits

This lecture covers the fundamentals of quantum metrology, focusing on superconducting devices and qubits. It delves into topics such as superconductivity, Josephson junctions, rapid single flux quantum electronics, and superconducting electronics. The lecture also explores various types of superconducting detectors, including transition-edge sensors, microwave kinetic inductance detectors, and nanowire-based detectors. Additionally, it discusses the principles of quantum computing, qubits as two-level systems, and the development of quantum processors from the Cooper Pair Box to the modern transmon qubit.
