Superconducting circuits and high finesse superconducting resonators are now used to observe cavity quantum electrodynamic effects usually seen only in atomic systems.  Recent improvements in the stability and coherence of superconducting qubits present the opportunity to couple quantum circuits to other quantum systems, including atoms, molecules, electrons, and even nanomechanical systems.  In this talk I will explain the features of quantum circuits that make them so promising for coupling to other systems and apply these principles to develop a new system using a superconducting circuit to investigate the motional and spin states of a single electron floating on superfluid helium. Finally, I will describe recent experiments towards creating a quantum memory using solid-state electron spins.
