Superconducting quantum computing is a promising implementation of quantum information that involves nanofabricated superconducting electrodes coupled through Josephson junctions. As in a superconducting electrode, the phase and the charge are conjugate variables, there exists three families of superconducting qubits, depending if the charge, the phase or neither of the two are good quantum numbers. This refers respectively to charge qubits, flux qubits, and hybrid qubits.
