| In the light of upcoming ideas for on-chip trapping and cooling of polar molecules (e.g. talk by R. Schoelkopf), I will discuss a scenario where a microwave cavity is strongly coupled to an ensemble of cold polar molecules. Compared to a single molecule qubit, the ensemble qubit benefits from a collectively enhanced coupling to the cavity and, similar as discussed for atomic ensembles, from the possibility to coherently convert it to 'flying' optical qubits. In this talk I will present an overview of the general feature of this system and the implementation of basic quantum information protocols. Further, I discuss some the relevant sources of imperfections, e.g. molecule-molecule collisions, and how these errors can be eliminated by freezing the molecules in a 1 or 2 dimensional dipole crystal. |
