The oneway quantum computer  a nonnetwork model of quantum computationA oneway quantum computer works by only performing a sequence of onequbit measurements on a particular entangled multiqubit state, the cluster state. No nonlocal operations are required in the process of computation. Any quantum logic network can be simulated on the oneway quantum computer. On the other hand, the network model of quantum computation cannot explain all ways of processing quantum information possible with the oneway quantum computer. In this paper, two examples of the nonnetwork character of the oneway quantum computer are given. First, circuits in the Clifford group can be performed in a single time step. Second, the realisation of a particular circuit the bitreversal gate on the oneway quantum computer has no network interpretation. (Submitted to J. Mod. Opt, Gdansk ESF QIT conference issue.)
