    "abstract": "While all bipartite pure entangled states violate some Bell inequality, the\nrelationship between entanglement and non-locality for mixed quantum states is\nnot well understood. We introduce a simple and efficient algorithmic approach\nfor the problem of constructing local hidden variable theories for quantum\nstates. The method is based on constructing a so-called symmetric\nquasi-extension of the quantum state that gives rise to a local hidden variable\nmodel with a certain number of settings for the observers Alice and Bob.",
