A recent study has explored maximum-confidence discrimination for ensembles of separable states, considering both global and separable measurements. The researchers demonstrated that global measurements outperform separable ones, thereby establishing nonlocality without entanglement (NLWE) in terms of confidence in a detection event. This fine-grained state-identification strategy maximizes the probability of a correct guess given a measurement outcome, representing a significant advance in understanding the fundamental properties of quantum mechanics beyond entanglement.
