Simulation of partial entanglement with one cbit and one M-box

TL;DR

This paper introduces a protocol that simulates correlations of nonmaximally entangled two-qubit states using minimal resources, specifically one cbit and one M-box, which are weaker than previously used resources.

Contribution

It extends existing protocols to simulate the non-local correlations of entangled states with fewer and weaker resources, namely a single cbit and an M-box.

Findings

Successful simulation of nonmaximally entangled states

Use of weaker resources than previous protocols

Extension to simulate non-local parts of correlations

Abstract

We present a protocol to simulate the correlations implied by nonmaximally entangled two qubit states. We extend this protocol to simulate the non-local part of these correlations. These protocols use single cbit communication and a single use of Millionaire box (M-box). To the best of our knowledge, these resources are weaker than those used in previous protocols using classical communication.
