Abstract

We describe recent experiments developed for investigating the interactions between superconducting phase quantum bits (qubits) and resonant cavities. Two-level system (TLS) defects within the junction barrier also couple to the qubits, adding more degrees of freedom, creating a rich multi-particle system for study.
