We do this by mapping CV cluster-state graphs onto two-mode squeezing graphs, which can be engineered into a single optical parametric oscillator (OPO). The desired CV cluster state is produced directly from a joint squeezing operation on the vacuum using a multi-frequency pump beam. This method has potential for ultracompact experimental implementation. As an illustration, we detail an experimental proposal for creating a four-mode square CV cluster state with a single OPO.4 pages, 1 figure; v2 improved discussion of the implications of our result; added discussion of finite squeezing effectsQuantum PhysicsUltracompact Generation of Continuous-Variable Cluster Statestext
