Query: Simulating entangled sources by classically correlated sources and
  quantum imaging   We discuss the problem of when a set of measurements made on an entangled
source can be simulated with a classically correlated source. This is discussed
in general and some examples are given. The question of which aspects of
quantum imaging can be simulated by classically correlated sources is examined.
