DC driven Josephson Quantum Circuits

Superconducting nanoelectronic devices based on the Josephson effect, and operating in the microwave frequency range have become key devices for quantum-state engineering and quantum computing, and quantum sensorics. The application of Lagrange and Hamilton methods to classical electric circuits and to circuit quantum electrodynamic circuits provides for a modeling approach. We present a quantum circuit model taking multiple DC driven Josephson junctions into account.
