About the module
Superconducting circuits are an important component of quantum-computing systems. In addition to providing one of the leading platforms for fabricating the fundamental units of quantum processing — qubits —, superconductors can be used to design circuit elements for manipulating and reading quantum states integrated into chips. This module introduces practical concepts of circuit quantum electrodynamics applied to superconducting systems. Participants will use computational tools to design and validate circuits for measuring qubit states. They will then fabricate the designed circuits using CBPF’s experimental infrastructure, including superconducting thin-film deposition and microfabrication processes for defining the desired structures.
