Query: The operational significance of the quantum resource theory of Buscemi
  nonlocality   Although entanglement is necessary for observing nonlocality in a Bell
experiment, there are entangled states which can never be used to demonstrate
nonlocal correlations. In a seminal paper [PRL 108, 200401 (2012)] F. Buscemi
extended the standard Bell experiment by allowing Alice and Bob to be asked
quantum, instead of classical, questions. This gives rise to a broader notion
of nonlocality, one which can be observed for every entangled state. In this
work we study a resource theory of this type of nonlocality referred to as
Buscemi nonlocality. We propose a geometric quantifier measuring the ability of
a given state and local measurements to produce Buscemi nonlocal correlations
and establish its operational significance. In particular, we show that any
distributed measurement which can demonstrate Buscemi nonlocal correlations
provides strictly better performance than any distributed measurement which
does not use entanglement in the task of distributed state discrimination. We
also show that the maximal amount of Buscemi nonlocality that can be generated
using a given state is precisely equal to its entanglement content. Finally, we
prove a quantitative relationship between: Buscemi nonlocality, the ability to
perform nonclassical teleportation, and entanglement. Using this relationship
we propose new discrimination tasks for which nonclassical teleportation and
entanglement lead to an advantage over their classical counterparts.
