We present a protocol to simulate the quantum correlations of an arbitrary bipartite state, when the parties perform a measurement according to two traceless binary observables. We show that log2(d) bits of classical communication is enough on average, where d is the dimension of both systems. To obtain this result, we use the sampling approach for simulating the quantum correlations.
