The course provides an introduction to superconducting qubits. Current hardware development for quantum computers is pursued in several technological platforms, where superconducting qubits seem one of the most promising technologies. The course will first introduce the theory for describing quantum mechanical motion of currents in superconducting circuits. It will then introduce currently employed qubit designs and tuneable couplers and explain how these are operated and how read-out is done. In the last part of the course novel error protected qubit designs will be discussed.
Students will learn to explain the relevant topics of the lecture and apply the methods to specific examples
