 Arageorgis (2013) gives an example of quantum field states entangled across two regions which nevertheless, he argues, fail to exhibit the same kind of  state nonseparability  as singlet and triplet spin states of a pair of quantum particles (see Maudlin 1998). But he suggests that his example does exhibit a kind of epistemological state nonseparability, in so far as an agent confined to a single region cannot determine its state by operations confined to that region. By applying the eigenvalue-eigenstate link to his example, Arageorgis (2013) argues that the energy of a particular compound quantum field system is not determined by the energies (or any other qualitative intrinsic properties and relations) of its component subsystems. He concludes that this example manifests physical property holism.
