    "abstract": "Quantum nonlocality is tested for an entangled coherent state, interacting\nwith a dissipative environment. A pure entangled coherent state violates Bell\u0027s\ninequality regardless of its coherent amplitude. The higher the initial\nnonlocality, the more rapidly quantum nonlocality is lost. The entangled\ncoherent state can also be investigated in the framework of $2\\times2$ Hilbert\nspace. The quantum nonlocality persists longer in $2\\times2$ Hilbert space.\nWhen it decoheres it is found that the entangled coherent state fails the\nnonlocality test, which contrasts with the fact that the decohered entangled\nstate is always entangled.",
