Measurement Based Quantum Computing (MBQC) is a very promising paradigm for the realization of a quantum computer, as it allows to separate the computation in the creation of an universal (independent of the performed algorithm) resource and the actual computing which is done by local measurements only. Possible resource states for single-qubit processing (quantum wires) and their couplings have already be classified using the formalism of Matrix Product States (MPS).

Cold atoms in optical super-lattices allow for controlled translationally invariant nearest-neighbor interaction between qubits, which can be described with the Margolus model of Quantum Cellular Automata (QCA). We explore the possibilities to create quantum wires with experimentally accessibly operations and discuss possible two-dimensional couplings.
