Circuit quantum electrodynamics
Circuit quantum electrodynamics is a theoretical framework which describes the quantum dynamics of the qubits and electromagnetic modes.
Overview
Superconducting circuits are metallic electrical circuits based on the Josephson effect, which lose all electrical resistance at cryogenic temperatures. Their supercurrents then become quantised and enable the realisation of quantum bits (qubits). These qubits possess electric dipoles, which strongly couple to electromagnetic modes in superconducting resonators.
