**Economical and noisy one-way quantum computing.** - Mark Tame

First, I would like to introduce several aspects of cluster-state quantum computing in the presence of noise and decoherence [1]. This will then allow me to talk in more detail about recent developments in economical strategies for quantum information processing [2, 3], that greatly improve the efficiency and scalability of the original "one-way model for quantum computation" [4, 5]. Then, I will go on to discuss some details concerning compact cluster configurations for two very interesting quantum algorithms [6, 7]. One of these [6] has recently been experimentally performed in Vienna and the other [7] is certainly feasible with current all-optical technology.
