Simulation of a Partially Entangled Two Qubit State Correlation with one PR-Box and one M-box

TL;DR

This paper introduces a minimal-resource protocol using a PR-box and an M-box to simulate quantum correlations of partially entangled two-qubit states in the worst case, improving on prior resource requirements.

Contribution

It presents the first minimal-resource simulation protocol for partially entangled two-qubit states using only one PR-box and one M-box.

Findings

Uses fewer resources than previous protocols

Achieves worst-case scenario simulation

Employs only one PR-box and one M-box

Abstract

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.
