Simulation of partial entanglement with nonsignaling resources

Understand

With the goal of gaining a deeper understanding of quantum non-locality, we decompose quantum correlations into more elementary non-local correlations.

• We show that the correlations of all pure entangled states of two qubits can be simulated without communication, hence using only non-signaling resources.
• Our simulation model works in two steps.
• First, we decompose the quantum correlations into a local and a non-local part.
