CLASSICAL PROTOCOL FOR SIMULATION OF SPIN MEASUREMENT CORRELATIONS OF BINARY SPIN-S SINGLET STATE.

In a recent paper [A. Ahanj et al., Phys. Lett. A368 (2007) 34], we gave a classical protocol to simulate quantum correlations corresponding to the spin-s singlet state for the infinite sequence of spins satisfying 2s + 1 = 2n. In the present paper, we have generalized this result by giving a classical protocols to exactly simulate quantum correlations implied by the spin-s singlet state corresponding to all integer as well as half-integer spin values s. The class of measurements we consider here are only those corresponding to spin observables, as has been done in the above-mentioned paper. The required amount of communication is found to be ⌈log2(s + 1)⌉ in the worst case scenario, where ⌈x⌉ is the least integer greater than or equal to x. [ABSTRACT FROM AUTHOR]
