    "abstract": "We investigate the amount of communication that must augment classical local\nhidden variable models in order to simulate the behaviour of entangled quantum\nsystems. We consider the scenario where a bipartite measurement is given from a\nset of possibilities and the goal is to obtain exactly the same correlations\nthat arise when the actual quantum system is measured. We show that, in the\ncase of a single pair of qubits in a Bell state, a constant number of bits of\ncommunication is always sufficient--regardless of the number of measurements\nunder consideration. We also show that, in the case of a system of n Bell\nstates, a constant times 2^n bits of communication are necessary.",
