title = "Symmetric extensions of quantum states and local hidden variable theories",
abstract = "The first systematic approach for constructing local hidden variable theories for quantum states, depending only on the number of local measurement settings for each observer is presented. The approach has yielded both numerically constructed local hidden variable theories for a variety of quantum states as well as analytical results for Werner states and a class of bound entangled states abase on real UPBs.",
