Interfacing quantum-optical and solid-state qubits

A generic models of soild-state qubits, coupling quantum-optical were investigated along with corresponding transfer were investigated. The trapped ions coupled to a charge qubit was also discussed. A superconducting cavity as the connecting element was introduced to enhance the coupling and to achieve compatibility between the different experimental setups. Instead of coupling na ion to a charge qubit via a cavity, coupling of two ions is also suggested.
