    "abstract": "There have been theoretical and experimental studies on quantum nonlocality\nfor continuous variables, based on dichotomic observables. In particular, we\nare interested in two cases of dichotomic observables for the light field of\ncontinuous variables: One case is even and odd numbers of photons and the other\ncase is no photon and presence of photons. We analyze various observables to\ngive the maximum violation of Bell\u0027s inequalities for continuous-variable\nstates. We discuss an observable which gives the violation of Bell\u0027s inequality\nfor any entangled pure continuous variable state. However, it does not have to\nbe a maximally entangled state to give the maximal violation of Bell\u0027s\ninequality. This is attributed to a generic problem of testing the quantum\nnonlocality of an infinite-dimensional state using a dichotomic observable.",
