Continuous variable (CV) entangled states of light serve as the foundation for a number of applications in quantum information science, such as quantum sensing, quantum computing, and quantum networking. To build a long distance multichannel quantum network or the resource states for CV quantum computing, multi-partite entangled states are needed. Here we report on the experimental scalable generation of CV multi-partite quantum correlated states. To this end, we leverage the multi-spatial mode properties of four wave mixing to implement a modified SU(1,1) interferometer that introduces quantum correlations between the different spatial modes. The expected quantum correlations involving conjugate variables are analyzed in terms of squeezing for all possible bipartitions. These results represent a first step toward the generation of multi-partite entangled states in connected graph states and show the expected connectivity of the graph.
