    "abstract": "It is shown that the ensemble $\\{p (\\alpha),|\\alpha\u003e|\\alpha^*\u003e\\}$ where $p\n(\\alpha)$ is a Gaussian distribution of finite variance and $| \\alpha\u003e$ is a\ncoherent state can be better discriminated with an entangled measurement than\nwith any local strategy supplemented by classical communication. Although this\nensemble consists of products of quasi-classical states, it exhibits some\nquantum nonlocality. This remarkable effect is demonstrated experimentally by\nimplementing the optimal local strategy together with a joint nonlocal strategy\nthat yields a higher fidelity.",
