Abstract
We present a local-hidden-variable model for positive-operator-valued measurements (an LHVPOV model) on a class of entangled generalized Werner states, thus demonstrating that such measurements do not always violate a Bell-type inequality. We also show that, in general, if the state can be obtained from with certainty by local quantum operations without classical communication, then an LHVPOV model for the state implies the existence of such a model for
