Query: Local tests of global entanglement and a counterexample to the
  generalized area law   We introduce a technique for applying quantum expanders in a distributed
fashion, and use it to solve two basic questions: testing whether a bipartite
quantum state shared by two parties is the maximally entangled state and
disproving a generalized area law. In the process these two questions which
appear completely unrelated turn out to be two sides of the same coin.
Strikingly in both cases a constant amount of resources are used to verify a
global property.
