Classical simulation of two spin-$S$ singlet state correlations involving spin measurements

Abstract

We give a classical protocol to exactly simulate quantum correlations implied by a spin-$s$ singlet state for the infinite sequence of spins satisfying $(2s+1)=2^n$, in the worst-case scenario, where $n$ 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 $lo{g}_{2}d$ where $d=2s+1$ is the dimension of the spin-$s$ Hilbert space.
