    "abstract": "We propose an experimental scheme that has the potential for large-scale\nrealization of continuous-variable (CV) cluster states for universal quantum\ncomputation. We do this by mapping CV cluster-state graphs onto two-mode\nsqueezing graphs, which can be engineered into a single optical parametric\noscillator (OPO). The desired CV cluster state is produced directly from a\njoint squeezing operation on the vacuum using a multi-frequency pump beam. This\nmethod has potential for ultracompact experimental implementation. As an\nillustration, we detail an experimental proposal for creating a four-mode\nsquare CV cluster state with a single OPO.",
