The complementary benefits of trapped ions and photons as carriers of quantum information make it appealing to combine them in a joint system. Cavity-QED provides a setting in which the quantum states of ions and photons can be interfaced efficiently. The most suitable scheme to use depends on the strength of the coherent ion-field coupling and the cavity damping rate. For moderate coupling, quantum entanglement may be generated probabilistically. Multiple ions are projected to an entangled state upon detecting photons emitted from the cavity. For stronger coupling, deterministic transfer of quantum states between ions and photons is possible, linking ionic qubit states with the two orthogonal polarization modes of the cavity. Entanglement of ions in a cavity may even be generated through the exchange of virtual photons. This requires the coupling to exceed the cavity damping rate. I will report on progress in the realization of these schemes at the University of Sussex.
