    "abstract": "We experimentally demonstrate the superior discrimination of separated,\nunentangled two-qubit correlated states using nonlocal measurements, when\ncompared with measurements based on local operations and classical\ncommunications. When predicted theoretically, this phenomenon was dubbed\n\"quantum nonlocality without entanglement.\" We characterize the performance of\nthe nonlocal, or joint, measurement with a payoff function, for which we\nmeasure 0.72(2), compared with the maximum locally achievable value of 2/3 and\nthe overall optimal value of 0.75.",
