Communication cost of simulating quantum correlations in a class of integer spin singlet states

الأصل · EN

We give a classical protocol to exactly simulate quantum correlations implied by a spin s singlet state for the infinite sequence of integer spin s=1,4,13,... satisfying (2s+1)=3ⁿ,where n is a positive integer.The required amount of communication is found to increase as log₃d² where d=2s+1 is the dimension of the spin s Hilbert space.
