    "abstract": "We investigate a new class of entangled states, which we call\n\u0027hyperentangled\u0027,that have EPR correlations identical to those in the vacuum\nstate of a relativistic quantum field. We show that whenever hyperentangled\nstates exist in any quantum theory, they are dense in its state space. We also\ngive prescriptions for constructing hyperentangled states that involve an\narbitrarily large collection of systems.",
