We investigate the amount of communication that must augment classical local hidden variable models in order to simulate the behaviour of entangled quantum systems. We consider the scenario where a bipartite measurement is given from a set of possibilities and the goal is to obtain exactly the same correlations that arise when the actual quantum system is measured. We show that, in the case of a single pair of qubits in a Bell state, a constant number of bits of communication is always sufficient--regardless of the number of measurements under consideration. We also show that, in the case of a system of n Bell states, a constant times 2^n bits of communication are necessary.

  1. Non-signaling assistance in prepare-and-measure scenarios with classical communication

    Non-adaptive non-signaling assistance simulates quantum communication in PM scenarios with a classical dit replacing a qudit, while adaptive NS advantages are confined to single-setting receiver cases.
