While all bipartite pure entangled states are known to generate correlationsviolating a Bell inequality, and are therefore nonlocal, the quantitativerelation between pure-state entanglement and nonlocality is poorly understood.In fact, some Bell inequalities are maximally violated by non-maximallyentangled states and this phenomenon is also observed for other operationalmeasures of nonlocality. In this work, we study a recently proposed measure ofnonlocality defined as the probability that a pure state displays nonlocalcorrelations when subjected to random measurements. We first prove that thismeasure satisfies some natural properties for an operational measure ofnonlocality. Then, we show that for pure states of two qubits the measure ismonotonic with entanglement for all correlation two-outcome Bell inequalities:for all these inequalities, the more the state is entangled, the larger theprobability to violate them when random measurements are performed. Finally, weextend our results to the multipartite setting.

Towards an equivalence between maximal entanglement and maximal quantum nonlocality
