2 00 6 Minimum communication cost of simulating quantum correlations is one cbit for all spin singlet states

We give a classical protocol to exactly simulate quantum correlations implied by a spin s singlet state for all spin values.The main charecteristic of the protocol is that Alice and Bob carry out measurements on 2× 2 subspace of the(2s+1)× (2s+1) Hilbert space.The required amount of communication is found to be one cbit which is independent of spin value,or the dimension of the corresponding Hilbert space and is obviously minimal.We find that the difficulty of simulation of entanglement increases with dimension of measurement operator,rather than the dimension of the Hilbert space.
