Computational appendix of "Bounding the sets of classical and quantum correlations in networks" [arXiv:1904.08943]

Code accompanying the article Bounding the sets of classical and quantum correlations in networks (arXiv:1904.08943), by Alejandro Pozas-Kerstjens, Rafael Rabelo, Lukasz Rudnicki, Rafael Chaves, Daniel Cavalcanti, Miguel Navascués, and Antonio Acín. The code provides tools for performing scalar extension of moment matrices in order to develop SDP hierarchies (in the spirit of the Navascués-Pironio-Acín hierarchy) that bound the set of correlations compatible with quantum causal networks with causally-independent parties.
