Abstract
We investigate a class of entangled states, which we call superentangled, that have EPR correlations analogous to those in the vacuum state of a relativistic quantum field. We show that whenever superentangled states exist in any quantum theory, they are dense in its state space. We also give prescriptions for constructing superentangled states that involve an arbitrarily large collection of systems.Keywords
