We propose a simple simulation of nonlocal quantum correlations among N qubits using a local hidden variable source with a positive probability distribution, given that each the N observers has access to a local negative bit. Notably, unlike the Toner-Bacon protocol, no exchange of classical bits between the observers is required. Moreover, our simulation can be extended to include Popescu-Rohrlich box correlations.
