The research detailed in this paper describes a Periodic Cluster State Generator (PCSG) consisting of a monolithic integrated waveguide device that employs four wave mixing, an array of probabilistic photon guns, single mode sequential entanglers and an array of controllable entangling gates between modes to create arbitrary cluster states. Utilizing the PCSG one is able to produce a cluster state with nearest neighbor entanglement in the form of a linear or square lattice. Cluster state resources of this type have been proven to be able to perform universal quantum computation.
