In the framework of microwave cavity QED, we propose two schemes to generate the two-dimensional 2×N and 3×N cluster states [1]. These states are produced between a chain of two-level Rydberg atoms in a deterministic way by using one or more bimodal cavities within the resonant atom-cavity interaction regime. In contrast to standard (single-mode) cavity schemes, such bimodal cavities possess two independent (orthogonally polarized) modes of the light field. We demonstrate that a 2×N cluster state can be generated efficiently with a single bimodal cavity, while two such cavities are needed to produce a 3×N cluster state. An extension of the scheme to generate two dimensional cluster states of arbitrary size is also possible.
