Query: Non-Locality distillation in tripartite NLBs   In quantum mechanics some spatially separated sub-systems behave as if they
are part of a single system, the superposition of states of this single system
cannot be written as products of states of individual sub-systems,we say that
the state of such system is entangled, such systems give rise to non-local
correlations between outcomes of measurements. The non-local correlations are
conditional probability distributions of some measurement outcomes given some
measurement settings and cannot be explained by shared information.These
correlations can be studied using a non-local box(NLB) which can be viewed as a
quantum systema. A NLB is an abstract object which has number of
inputs(measurement settings) and number of outputs(outcomes), such NLBs can be
both quantum and super-quantum. The correlations are of use in quantum
information theory, the stronger the correlations the more useful they are,
hence we study protocols that have multiple weaker non-local systems,
application of these protocols to weaker systems may result in stronger
non-local correlations, we call such protocols non-locality distillation
protocols. In our work here we present non-locality distillation protocols for
tripartite NLBs specifically GHZ box and class 44,45 and 46 of no-signalling
polytope.
