Simulation of a Partially Entangled Two Qubit State Correlation with one   PR-Box and one M-box
  We present a protocol to simulate the quantum correlation implied by non maximally entangled two qubit states, in the worst case scenario. This protocol makes a single use of PR-box and a single use of Millionaire box (M-box). To the best of our knowledge, the resources used in this protocol are weaker than those used in previous protocols and are minimal in the worst case scenario.
