Classical simulation of two spin- singlet state correlations involving spin measurements
We give a classical protocol to exactly simulate quantum correlations implied
by a spin- singlet state for the infinite sequence of spins satisfying , in the worst-case scenario, where is a positive integer. The
class of measurements we consider here are only those corresponding to spin
observables. The required amount of communication is found to be
where is the dimension of the spin- Hilbert space.Comment: 7 pages,no figures, To appear in Phys.Lett.A. Accepted in Phys.Lett.
