In this paper we discuss the prospects of quantum information processing involving forbidden transitions in the inner shell of the rare-earth elements. We shall derive the selection rule for such transitions and investigate the prospects for rare-earth based quantum information procession that employ dipole-dipole forbidden transitions. The long decoherence time, degree of entanglement, lossless interconnectivity of these transitions will be model and their impact on quantum information processing will be examined.

We will focus here in particular on the engineering the open system dynamics of many particles by a controlled coupling to an environment. We will discuss both the basic theoretical concepts as well as their physical implementation with cold Rydberg atoms and ions.We conclude with an outlook on prospects of quantum information processing of hybrid atomic solid state systems, in particular the coupling of cold atomic clouds to nanomechancial oscillators.
